PURPOSE: A method for group buying with lowest prices according to points is provided so that bid participants can be thrilled by difference of a purchasing price, by enabling the earliest bid participant to purchase a group buying product in a minimum price and the latest bid participant to purchase the group buying product in a maximum price. CONSTITUTION: A purchaser becomes a member of a group buying service company by inputting personal information(S10). After the member registration procedure, the member reads group buying information in a group buying information screen by inputting a domain of the group buying service company through a personal computer(S11), and clicks a group buying bid participation button(S12). The group buying service company confirms whether the member participates in a group buying bid, and temporarily holds maximum price points from a member account(S14). Thereafter, the group buying service company makes a bid list and secretly decides a contract price according to the maximum price point bidding order(S15)(S16). After the group buying closing date, the contract price is displayed on the web site screen of the group buying service company, or transmitted to E-mail addresses of the members(S17).
