A bidding fee auction, also called a penny auction, is a type of all-pay auction in which participants must pay a non-refundable fee to place a small incremental bid. When time expires, the last participant to have placed a bid wins the item and also pays the final bid price, which is usually significantly lower than the retail price of the item. The auctioneer makes money in two ways: the fees for each bid and the payment for the winning bid.

How it works

Participants pay a non-refundable fee to purchase bids. Bidding on an auction raises the cost of the item by a fixed amount and typically also extends the deadline of the auction. The game is a brinkmanship game: each successive bid lowers the value of the reward, and the last player to decide to place a bid and lower the value of the reward wins that reward.

Once the auction is over, the auctioneer collects the final cost of the item in addition to the monies already collected by selling bids.

Each bid increases the price of the item by a small amount, such as 0.01 USD (1¢) or 0.01 GBP (1p), and extends the time of the auction by a few seconds. Bid prices vary by site and quantity purchased at a time, but generally cost 10–150 times the price of the bidding increment.[1] Due to the possibility of participants spending a lot of money and still losing an auction, or spending more than the retail value of the item they end up winning, some analysts have criticised the model.[1][2][3][4]
