How do auctions work?

BuyingLast reviewed Oct 8, 2026

A bid must beat the highest bid by at least the minimum increment (the default is $1), and your wallet must hold the bid amount when you place it.

  • Some auctions have a buy now price. A bid at or above it counts as buying now, and the listing is held for you while you check out.
  • A seller can set a hidden reserve. The reserve has to be met for the auction to complete.
  • When an auction ends, only the highest bidder can buy, within 72 hours. If they do not, the seller can relist.
