Can I retract or cancel my bid?
As a general rule, you can't retract, remove, or cancel a bid. When you place a bid, you agree to pay for the item if you're the winning bidder.
A bid on eBay is considered a contract, and you're obligated to purchase the item.
If you won an item and you no longer want to buy it, contact the seller
However, honest mistakes sometimes occur. You can retract a bid if you have a valid reason for doing so as defined by our policy, and you retract the bid within the required time period.
Valid reasons for retracting a bid include:
You accidentally entered the wrong bid amount. For example, you bid $99.50 instead of $9.95. If this happens, you need to reenter the correct bid amount right away.
The item's description changed significantly after you entered your last bid. For example, the seller updated the details about the item's features or condition.
You can't reach the seller by telephone or email.
Changing your mind isn't a valid reason for retracting a bid. Review listings carefully before bidding.
