Description

{Method for cooperative buying with the lowest price through internet}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to commerce using the Internet, and more particularly, to a method and apparatus for joint purchase at a lowest price using the Internet.

With the advent of the Internet, there are various forms and ways in which consumers become the subject of commerce and determine prices.

The methods and systems used to date come in various forms, such as joint purchase, reverse auction and price comparison. However, these methods and systems still have their limitations.

Co-purchase system is a way to trade the price by gathering a number of consumers who want to buy the same goods jointly. However, in this method, the seller often decides and purchases the goods and the price in advance, so the buyer is not given a substantial discount. In a more advanced form, a method of pre-determining what consumers want to buy has appeared, but there is a problem that it is difficult to find consumers who want the same model and specifications at the same time and the price competitiveness is not proven. Co-purchasing has been attempted by magazines and community clubs before the Internet appeared, and it is a method for gathering a lot of buyers for the same goods and purchasing the goods cheaply. In this way, there is a method developed by accompany in the US, which is one of the most ideal models to date. This method has an advantage in that the price of the joint purchase object falls when the number of desired purchasers reaches a certain number. However, this method has a pre-determined purchase price according to the number of buyers, which is less flexible than the reverse auction method that can lower the price due to competition among various companies. There is a disadvantage that does not give the buyer a credibility.

Another way is to compare prices at each Internet shopping mall site. An internet product search engine is used to find the cheapest sites among the internet shopping mall sites. However, this product search engine does not satisfy the searcher in providing all the price information of the Internet site which is increasing day by day, and the search robot does not satisfy the technical problem and the database format that may be different in various sites. In addition, the use of a search robot imposes an excessive load on the shopping mall site that is the target of the search, and even a case where the operation of the shopping mall site is stopped because the Internet server on which the shopping mall site is constructed is down. Due to these problems, users who are not satisfied with the price are suffering from having to go to the cheapest site for the necessary items.

Another method is reverse auction. A reverse auction is a method in which a buyer presents an item and a desired price, and a seller who bids the lowest price for the offer is bid and sells the item. This method has a problem in that it is difficult to induce a lot of goods trading, and the kind of goods that can offer a price that satisfies the consumer is limited to inventory goods and the like.

The technical problem to be solved by the present invention is that, in order to solve the above problems, it is possible to propose a reliable price, only a small number of buyers of the co-buyer need to search only a few revisions of the Internet for purchase, It is to provide the lowest price joint purchase method using.

Informing members of the site; (e) a member wishing to purchase access and apply for the final purchase of the goods; (f) determine the final selling price and the final seller corresponding to the case determined by the number of members who have applied for the final purchase by the deadline and the number of the purchasers, and the final selling price to the final purchase application members. Informing the information including; And (g) characterized in that it comprises the step of the final purchase application member pays the amount, and delivers the goods to the member.

At this time, the step (g) is the final purchase request member delivers the amount of the final selling price plus the fee corresponding to the difference between the lowest price and the final selling price to the site, the site is the finalized final The seller is notified of this, and the final seller delivers the goods to the final purchase application member, and the site is characterized in that the final sale price transfer amount to the final seller.

Or, if the final purchase request member belongs to a predetermined group, before the step (a), further comprising the step of including information about the group to which each member belongs to the member information of the Internet site, In the step (g), the site notifies the last purchase requesting member of the last purchase requesting member to the affiliated entity and the final seller notifying the entity to which the final purchase requesting member belongs to the purchased goods. Delivering to the entity; And the final purchase request member delivers the sum of the final selling price to the group to which the final purchase requesting member belongs to the fee corresponding to the difference between the lowest price and the final selling price set in step (b) and receives the delivered goods. And, the group delivers the amount of money received, except for a predetermined fee from the delivered amount to the site, the site characterized in that it comprises the step of delivering the amount corresponding to the final selling price to the end seller.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 illustrates a flow of joint purchase according to an embodiment of the present invention. Explain this. This method represents an individual participating in a joint purchase.

In the joint purchase site accessed through the Internet, enter information including the lowest price that a purchaser who is a member knows about the item that he / she wants to purchase by accessing the site; If the user chooses to approve the purchase of the article and wishes to purchase the article, or if the article can be purchased at a price lower than the minimum price, information including the price is input (step 10).

After the predetermined application period, each of the above-mentioned purchasers and predetermined sellers who have previously registered information on the site including information including the number of purchasers who want to purchase the goods and the lowest purchase price of the goods determined for the predetermined period of time. (Step 11), the sellers sell prices to the site for a predetermined bid period corresponding to a plurality of cases, which are determined by the sellers according to the number of desired purchasers and the number of final purchase application members to be determined later. Present (step 12).

After each of the predetermined bid periods, the seller who has determined the lowest selling price and the lowest selling price in each case is determined, and the information including the selling price for each case and the deadline for the final purchase request are determined. The members are informed (step 13), and the member who wishes to purchase accesses and requests the site to make a final purchase (step 14).

The final selling price and the final seller corresponding to the case determined by the number of members who applied for the final purchase by the deadline and the number of the purchasers are determined, and the final selling price is included in the final purchase application members. Informing the information (step 15), the final purchase application member delivers the sum of the final selling price and the fee corresponding to the difference between the lowest price and the final selling price to the site, and the site is the determined final seller. The final seller delivers the goods to the final purchase application member, and the site delivers the amount corresponding to the final selling price to the final seller (step 16), where the joint purchase is made.

The steps are further explained.

You can access the Internet site for the joint purchase of which you are a member through the Internet, and through the menu prepared for the joint purchase, the model name, model number, specifications of the item and Enter the lowest price you know, the name of the site selling the lowest price, and a category. Since each shipping site has a different shipping charge for the goods purchased, the lowest price you know may include the shipping price plus the shipping price. If you can get a picture of the item, you can enter a picture.

The type of item desired to be purchased may be selected from the menu for the joint purchase, for example, a selection submenu of the item even if the member who wants to purchase is not entered.

The article serial number, the input date and the ID of the user may be automatically entered in the menu for the joint purchase.

The entered item may be displayed in the list of items for the buyer of the category.

2 illustrates an example of a screen showing the joint purchase related information to members after inputting a product to be jointly purchased.

The reference number 20 indicates that the article which you wish to purchase jointly is a printer among peripherals in computer related articles. If a member wishing to purchase selects the relevant menu, the screen for the joint purchase of a printer will be displayed.

For example, if a member who wants to purchase an item called 'HP Deskjet 610C' applies as described above, the item will be registered as shown by reference numeral 21 of FIG. At this time, the time to end the purchase application may be determined by a member registered for the first purchase, and may be automatically set to a time after a predetermined time has elapsed since the time of the first application in the joint purchase menu. This state may be indicated by a step of 'lowest price input' as in the current step 21 of FIG. 2.

When a member who wants the same type of printer enters the printer item of the co-purchase and selects the item name, detailed information about the object is displayed on the screen from the database prepared by the program driving the co-purchase menu. This database may be created based on the information entered by the members applying for the purchase of the item. When the member who wants to purchase the item after seeing this detailed information wants to make a purchase and displays it, for example, the user wishes to make a purchase by clicking the 'I want to participate in the purchase' button, and the screen shown in FIG. The number of applicants will increase.

If you know a site that sells cheaper items for the same item, the member who wants to buy it enters the site's name and lowest price. The site name and the lowest price are updated here, but the information about the previous price and the selling site is preferably stored in the database. If the updated lowest price is not true, the updated information is deleted and the lowest price is displayed as the lowest price on the screen except for the previous lowest price or the deleted lowest price.

Eventually, the lowest price offered during the application period is finally posted, and a number of purchasers go to each shopping site to find out the site and price at which the item is sold at the lowest price. Therefore, with the efforts of a few directly interested parties who want to purchase a product, it is possible to obtain a result of comparing and analyzing prices of more sites and more sophisticated than a robot for product comparison search. In addition, each member is more efficient than searching for the cheapest shopping mall, and unilaterally participates in purchasing the product at a lower price with more information than the seller determines the price.

If there are enough buyers in the future (there may be a number of criteria for determining the sufficient number), free purchase for members who originally selected this item and initiated the joint purchase and the lowest priced member. Will be able to be given a reasonable reward.

After the designated application period, information including the name of the item, the number of applicants who have applied for it, and the lowest price established through the above-mentioned process and the site selling at the lowest price are obtained through the same method as e-mail. It is delivered to certain merchants registered on the site. At this time, in the screen as shown in FIG. 2, as shown by reference numeral 22, the current step may be displayed as 'start bidding'.

As mentioned above, the seller who has been informed of the desired purchase item, the number of desired purchasers, the lowest price and the site selling at the lowest price can check the lowest price at the corresponding site and notify the co-purchase site if it is different from the fact. In the joint purchase site, it is desirable to check this, and if it is confirmed as true, delete the lowest price notified and post the next lowest price on the screen as shown in FIG.

Seller will present the selling price at a price lower than the lowest price notified. At this time, the seller may offer a different price for each case determined according to the number of notified purchasers and the final number of members applying for final purchase.

For example, different prices can be offered for each case as follows:

1) When the number of final purchase applicants is 0.3 times the number of desired members

2) When the number of final purchase applicants is 0.5 times the number of desired members

3) When the number of final purchase applicants is 0.7 times of the desired members

4) When the number of final purchase applicants is 1.0 times the number of desired members

5) When the final purchase applicant is 1.5 times the desired membership

6) When the number of final purchase applicants is 2.0 times or more of the desired members

The seller offers bids for each of the six cases, and the bids are made public so that other sellers know. It is presented during a given bid period. The other seller may refer to this to determine the price he proposes, and it is desirable that the seller who posted the price can modify the price presented during the bidding period.

After the bidding period has passed, the seller and the price who presented the lowest price for each of the six cases above are determined as the lowest price. In each of the six cases, the bidder who gave the lowest price may be different.

By presenting different prices according to the number of final purchase applicants, the transaction can be made at a price satisfactory to both the seller and the buyer.

According to the present invention, the present invention is more effective than the conventional method in that the number of desired purchasers is determined in advance, and the price of the bidding result of the product may be different depending on the number of buyers finally determined by receiving the reverse auction bidding of the seller. It can be said to be flexible. From the buyer's point of view, the more people who buy, the cheaper they can buy, and the seller can adjust the price according to the number of people who buy.

If no seller is able to offer a price below the lowest price notified, co-purchases will no longer be possible, but buyers will be informed of the best selling site and will be satisfied if they make an individual purchase on that site. It will be possible.

The price for each case determined as described above is informed to the desired members and all members of the joint purchase site that the bid of this product has been determined through an e-mail method. The application deadline will be announced. In this case, as shown by reference numeral 23 on the screen as shown in FIG. 2, 'purchasing application' is displayed, and the purchase application deadline will be displayed as the time of the end of the purchase application.

The member applying for the final purchase accesses the co-purchase site through the Internet, selects the item, for example, clicks and selects the final purchase hope button to apply for the final purchase, which will increase the number of applicants. . In addition, according to each case determined by the number of members who applied for the final purchase and the number of first purchasers, the selling price of reference numeral 23 of FIG. 2 may be changed to the price of each case presented by the seller as described above.

If the final purchase applicant is less than 30% of the number of applicants initially informed of the seller, the auction may be decided to be cancelled.

After the deadline for applying for purchase is determined and the number of final purchasers is determined, the final seller who presents the lowest price is determined according to the final purchase applicant and the first purchaser.

The information including the final selling price determined as described above is delivered to the member who applied for the final purchase, and the final purchase applicant deposits the fee and the price of the product on the joint purchase site or the site operator. The fee may be set at, for example, 30% of the difference corresponding to the amount of the difference between the lowest price and the final selling price notified to the seller. Of course, at the co-purchase site, before the co-purchase begins or before the co-purchase begins, the final purchase applicant should notify each member that they must pay the fees calculated in this way. At this time, if the member who wishes to purchase at step 10 applies for the final purchase at step 14, it is preferable to be able to discount the fee determined as described above to the member. This will be one way to encourage members who want to make their first purchase to make a final purchase.

In addition, if the end seller also pays a predetermined fee, the buyer's fee may be reduced.

Once the deposit is confirmed, the co-purchase site contacts the end seller, who sends the goods to the end purchase applicant. In this case, as shown by reference numeral 24 of FIG. 2, the current step will be displayed as 'deposit confirmation' or 'shipping goods'.

In the joint purchase site, the final purchase applicant receives the goods and confirms that there is no defect in the goods, and delivers the amount corresponding to the final selling price to the seller.

In order to facilitate the process of joint purchases, members who apply for a final purchase that has not made a deposit after more than one final purchase application are deprived of membership, and sellers who deliver specifications and other items to the final purchase applicant are deprived of the seller registration. It is desirable to be able to prevent future participation in joint purchases.

The method described above describes an example of how individuals can make a joint purchase by joining the joint purchase site as a member.

3 illustrates a flow of collective purchase of a group through the Internet according to another embodiment of the present invention. Explain this.

In the joint purchase site accessed through the Internet, the member information of the member is included in the member information of each member (step 30).

Input information including the lowest price that a purchaser who is a member wants to access the site and want to purchase on the site, and for a predetermined application period, a buyer who is another member who wants to purchase the product If you choose to approve and wish to purchase, or if the item can be purchased at a price lower than the minimum price, input information including the price (step 31).

After the predetermined application period, information including the name of the article, the number of purchasers who want to purchase the article, and the lowest purchase price of the article determined during the predetermined application period are pre-registered in the respective purchasers and the site. To the predetermined sellers (step 32), and the sellers sell prices to the site corresponding to a plurality of cases determined by the number of purchasers and the number of final purchase application members to be determined later. Present during the predetermined bid period (step 33).

After the predetermined bidding period has passed, the seller of the site determines the seller who presented the lowest selling price and the lowest selling price in each of the above cases, and includes information on each case including the selling price and the deadline for the final purchase application. Notify the user (step 34), the member who wants to make a purchase and access the site to apply for the final purchase (step 35), and is determined according to the number of members who have applied for the final purchase by the deadline and the number of the applicants. The final selling price corresponding to the final selling price and the final seller are determined, and the final purchase application members are informed of the information including the final selling price (step 36).

The joint purchase site informs the group to which the last purchase requesting member belongs to the last purchase requesting member and informs the end seller of the group to which the last purchase requesting member belongs and delivers the purchased goods to the group. (Step 37), the final purchase application member delivers the sum of the final selling price and the fee corresponding to the difference between the lowest price and the final selling price to the organization to which the member belongs and receives the delivered goods. The group transfers the amount of money received from the received amount excluding a predetermined fee to the site, and the site transfers the amount corresponding to the final selling price to the end seller (step 38). The process of joint purchase through the collective purchase site with the group is completed.

The steps are explained in detail. A description of the steps substantially identical to the steps of FIG. 1 already described above will be omitted.

One of the biggest challenges of existing e-commerce sites is the cost of transportation. By using e-commerce, the intermediate distribution step is reduced, so the price of goods is cheaper, but if the cost burden of sending to individuals from all over the country is added, it is impossible to sell the goods at a low price. Therefore, in order to solve this problem, there have been ways in which customers go directly to the chain stores or convenience stores in each region, but the profits from the chain stores or convenience stores are small and if the mass sales are not made, the shipping cost is still burdened. Inconvenient, too, can not expect a great effect.

In the present invention, a relatively high Internet usage and purchase demand, such as schools and apartments, the buyer can go to the goods purchased without any inconvenience in space and time, and the group to which each individual belongs (for example, student council, apartment Residents' Associations, etc.) provide ways to induce joint purchases for large groups that can be responsible for profitable businesses such as advertising and sales.

First of all, the apartment residents' local government can make a profit business, and when the goods are delivered to the management office, they can be distributed. There is a student council in the university, which can be distributed by delivery to the student council office. From now on, the application of the present invention will be described taking an example of the student body of a university.

In the co-purchase site, contracts for supply of goods with university student councils across the country are applied for co-purchase of students from their universities through the Internet. Student councils will be able to take charge of offline advertising, such as college bulletin boards or school newspapers, without burdening their own profitable businesses. When the final purchase is decided, the student council receives the payment from the student who applied for the purchase and notifies the co-purchase site operator. The co-purchase site operating company to deliver the goods to the student center, the student council to check the goods and then deposit the price of the goods to the Internet operating company. Students are welcome to pick up items at the Student Council or at a designated location, such as the Student Union. And the joint purchase site operating company delivers the goods price to the goods supplier.

The procedure of such joint purchase is as follows.

In the joint purchase site, information about the organization to which the member belongs is inputted from the member and included in the member information. Entering information about this organization may be required at the time of initial membership or when needed. In this embodiment, since the university is described, in this case, information about the school attended will be input.

Since the member applies for a joint purchase and the final selling price is determined (steps 31 to 36) is substantially the same as the steps (steps 10 to 15) of the method according to FIG. 1, further description is omitted. do.

The final sale price is notified to the final purchase requesting member (step 36), and the student council of the school to which the final purchase requesting member belongs is notified that the final purchase requesting member will purchase the item. In addition, the end seller is notified of the school to which the last purchase application member belongs, so that the number of joint purchases for each school is delivered.

When the goods are delivered to the student body, the student who applied for the final purchase receives the goods at the place designated by the student body or the student body and adds a fee corresponding to the difference between the lowest price and the final selling price initially delivered to the seller to the final selling price. Pay the appropriate amount to the student body. The student council transfers the amount excluding the prescribed fee to the joint purchase site, and the joint purchase site passes the amount corresponding to the final selling price to the final seller.

In addition, as in the case of Figure 1, as a way to induce a member who applied for the initial purchase until the final purchase application, if the member who wishes to purchase in step 31, apply for the final purchase in step 35, It is desirable to be able to give the member a discount on the fee as defined above.

In order to facilitate the process of joint purchases, members who apply for a final purchase that has not made a deposit after more than one final purchase application are deprived of membership, and sellers who deliver specifications and other items to the final purchase applicant are deprived of the seller registration. It is desirable to be able to prevent future participation in joint purchases.

Figure 4 illustrates the flow of the embodiment described above centered on the student, the student body, the joint purchase site and the seller.

In order to minimize the transportation cost burden, which is the biggest problem of e-commerce, the solution is to select a place that members frequently visit and use it as a base for advertising and transportation. In particular, since the student council can advertise to students at no cost, and the environment is easy for students to use the Internet in school, it is possible to form a huge commerce market by promoting sales to universities in the beginning. can do. Since payment is made to students and payment is received after confirmation of receipt of goods, even if it is an early stage internet site, it can be purchased with confidence, and the cost of building a site can be a big advantage.

Students only need to do some hard work to find the cheapest site and go to the student council to find the item, such as checking the price of the item on the cheapest site on the Internet to buy the item.

The method according to the present invention can be applied to an apartment community, a middle school, and a high school, and can be extended to a community portal for college students or university alumni associations through various events that induce exchange between student associations.

According to the present invention, members can directly find information for price comparison, and overcome the limitations of sites that compare prices. And since the reverse auction proceeds based on the lowest price thus obtained, it is possible to purchase a product at the lowest price through a large purchase. If a reverse auction is found, members will still be able to purchase information about the site selling the lowest price. The more the final buyer who suggested the final purchase intention, the lower the price, so the member himself advertises to other participants. While it is not possible to meet all the specifications that each member wants, the model is the ideal joint purchase model for consumers who value the price of certain products.

Hereinafter, another method of collective purchase of a group through the Internet will be described. 5 illustrates a flow of a method for collective purchase of a group via the Internet according to another embodiment of the present invention. Explain this.

The information on the organization to which each member belongs is included in the member information of the Internet site (step 50). On the site, a purchaser who is a member accesses the site, enters information including a minimum price that the member knows about the item he / she wants to purchase in a menu that can be viewed and entered, and purchases the item for a predetermined application period. A buyer who is another member intending to purchase the item is selected to approve the purchase of the item, or inputs information including the price if the item can be purchased at a price lower than the minimum price (step 51).

After the predetermined application period has passed (step 52) to determine the lowest purchase price of the item of the input price, and to sell the article at a price less than the minimum purchase price to the members of the site for a predetermined period (Step 53). Members who wish to purchase at the price indicated in step 53 access the site and apply for a predetermined period of time (step 54). Notify the organization to which the last purchase requesting member belongs to the last purchase requesting member to purchase, deliver the purchased goods to the organization (step 55), and the final purchase requesting member to the organization to which the member belongs to reference 53 In step 56, the group delivers the amount of money included in the price and receives the delivered item, and the group transfers the amount excluding the predetermined fee to the site.

Explain each step in detail. In FIG. 1 or FIG. 3 described above, the description of the steps substantially the same as the steps will be omitted.

Steps 50 and 51 are the same as those described above. Using the result of step 51, the lowest price of the item to be jointly purchased is determined by the price voluntarily found by the members of the site (step 52).

In the method of FIG. 3, the seller goes through the seller, but the method of FIG. 5 does not go through the seller but sells the goods directly from the site where the joint purchase is initiated. The price below the price determined in step 52 is presented to the members of the site for a predetermined period (step 53). This suggestion may be sent to all members by e-mail or posted on a joint purchase bulletin. Members who like this price apply for a purchase (step 54). You can make a purchase request menu on the joint purchase bulletin board and click the mouse to receive the final purchase request.

In order to facilitate the purchase of a reference at step 51 and to find a cheaper price, a member who applies for a purchase at step 51 and also makes a final purchase may benefit from price or otherwise. will be.

After a predetermined period of time, the member who applied for the final purchase is confirmed, and the information about the member is notified to the group to which the member belongs and the goods are sent to the group (step 55). It is also desirable to notify the member via e-mail that the item has been sent to the organization.

The member receives the goods that arrive at the organization and pays the organization an amount that includes the price given in step 53. The organization transfers the amount excluding the fee from the amount to the site (step 56). The amount paid may be the same as the price quoted, or shipping charges may be included separately. If shipping charges are included separately, it is advisable to indicate them at step 53.

In addition, as in the case of Fig. 1 or 3, as a way to induce a member who applied for the initial purchase until the final purchase application, the member wishing to make a purchase in step 51 the final purchase in step 54 If you apply, it is desirable to be able to discount the fee set out above.

The method of FIG. 5 may also be applied to an apartment community, a middle school, or a high school, and may be extended to a community portal for college students or college alumni associations through various events that induce exchange between student associations.

According to the present invention, members can directly find information for price comparison, and overcome the limitations of sites that compare prices.

Although the embodiments of the present invention as described above have been described by way of example with reference to the drawings, this example is for understanding the spirit of the present invention and the spirit and scope of the present invention are not limited to the above examples, It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the scope of the matter allowed.

According to the present invention, the seller purchases the price flexibly according to the number of people who have applied for a joint purchase for the required goods by accessing the joint purchase site through the Internet and the number of those who have applied for the joint purchase and finally apply for the purchase. By determining the joint purchase price, the buyer can purchase the goods at the lowest price with minimal effort to compare prices, and the seller can also supply the goods in large quantities according to the quantity of the goods sold.

In order to compare prices of products, the members directly searched for information to overcome the limitations of the price comparison sites, and based on the lowest price thus obtained, the reverse auction proceeds, so you can purchase the products at the lowest price through large quantity purchase.
