Your bids affect how other users bid for an item and the item’s final selling price. We carefully investigate all bid retractions to determine whether they are appropriate and conform to the rules for buyers. Abuse of bid retractions can result in the suspension of your account.
Bidding is meant to be fun, but remember that each bid you place enters you into a binding contract. All bids are active until the auction ends. If you win an auction item, you’re obligated to purchase it.
Don’t bid on identical items in different listings if you only want one item. If you win both, you’ll be obligated to buy both.
If you’re outbid on an item, wait until the listing has ended before placing a bid on an equivalent item. If the bidder who won doesn’t complete the transaction for any reason, you could become the winning bidder.
If you’re blocked from bidding on any auction, you cannot bid using another user ID.
