How a penny auction works
A penny auction, also called a pay-per-bid or bidding-fee auction, looks like an ordinary auction but the money flows differently:
- You buy bids in advance. Bids are sold in packs, and each bid costs a fee — commonly around $0.50 to $1 per bid — whether you win or lose.
- Each bid raises the visible price by a penny. The "penny" in the name is the price increment, not the cost of bidding.
- Each bid resets the countdown timer, typically adding seconds to the clock, so an auction can run far longer than it first appears.
- The last bidder standing when the timer hits zero wins — and then pays the closing price on top of every bid fee they already spent. Shipping and fees may be added as well.
- Everyone who bid and lost keeps nothing. Bid fees are non-refundable, so losing bidders pay for no item at all.
The math the headline hides
Penny auction pages advertise the closing price — "sold for $20!" — but that number leaves out the bid fees, which are where most of the money goes.
Illustrative arithmetic (not a real auction): an item closes at $20. Because the price rises one cent per bid, that closing price represents 2,000 bids. If each bid cost $1, then $2,000 in bid fees changed hands for an item that "sold" for $20 — and the winner still has to pay the $20 on top of whatever they personally spent on bids.
The operator collects bid fees from every bidder, not just the winner. On a busy auction, total bid fees can run several times the retail value of the item. That is why the business works even when the "winning" price looks tiny.
Why the "90% off" headline misleads
The advertised discount compares the closing price to the retail price. It does not count the bid fees paid by all participants along the way, and it does not count what you personally spent to get there. A $20 closing price on a $200 item is not a 90% saving if you spent $80 on bids to win it — and it is a loss, not a saving, if you spent $80 on bids and lost.
Red flags to watch for
- Auctions that never seem to end. The U.S. Federal Trade Commission has warned that some sites use automated bidding programs that keep bidding to extend auctions and keep people spending. If an auction stretches for hours with the timer constantly resetting, step back.
- Bid packs that vanish. Pre-purchased bids are usually worthless if a site closes, and pending shipments or disputes can be hard to resolve after an operator disappears.
- Cards charged beyond the bid pack. Watch for registration or "free bid" offers that put a card on file and then auto-charge for more bid packs. Read the billing terms before registering anywhere.
- Costs after the win. Some wins still carry shipping charges, handling fees, or transaction fees on top of the closing price and your bid fees.
- Pressure to keep going. Money already spent on bids is gone either way. Spending more to "make it back" is how small losses become large ones.
More lottery than auction
The Federal Trade Commission has said that in many ways penny auctions are more like lotteries than traditional online auction sites: you pay to play, with no guarantee of receiving anything. Treat them that way — as a gamble with the odds stacked against you, not as shopping.
What to do instead
- Set a hard total budget before you bid — and count bid fees, not the closing price. Decide the most you will spend on bids, total, and stop there whether you are winning or losing.
- Buy outright when you want the item. Ordinary retailers, classifieds, and local marketplaces sell the same kinds of goods without a per-bid fee. One local option is the Binghamton Marketplace.
- Skip "free bid" sign-ups that want your card. A genuinely free offer does not need billing details.
If you already paid and feel misled
- Report it to the FTC at ReportFraud.ftc.gov.
- Contact your bank or card issuer about charges you did not authorize or did not understand.
- Save screenshots of the auction page, the billing terms, and your receipts.
