Provided are an auction method and server that enable a seller and bidders to determine the price of a product at their own discretion by enabling the bidders to participate in a bid between the lowest price offered by the seller and the highest price of the product, and give benefit to both the seller and successful bidders by applying the successful bid price of a lowest successful bidder to all the successful bidders as a sale price. The auction method includes maintaining, at an auction server, a database of the highest price of a specific product, the lowest price offered by a seller, and the limited number of successful bidders, receiving, at the auction server, bidding information including bid prices for the specific product between the lowest price and the highest price from bidders, selecting, at the auction server, a lowest successful bidder from among the bidders in consideration of the limited number of successful bidders and the bidding information when a predetermined bidding time elapses, and requesting, at the auction server, payment from all successful bidders using a successful bid price of the lowest successful bidder as a sale price on the basis of bidding information about the lowest successful bidder.
