If you make a bid and you realize quickly that it was in error, the auction house may let you out of the bid and go to the next highest bidder. However, this is not always the case. At a live auction, a bid represents a legal obligation. 6 It's also possible that you could get sued if you try to back out of an auction.
As a seller, you can cancel bids on eBay in the following situations: when you agree to a buyer's request, when the item isn't available anymore, if you made an error in the listing, or if you're concerned the bidder might be fraudulent.
If the auction has finished, you can contact the winner and, if they agree, you can cancel the order. You can only end auction listings with bids one at a time by selecting a valid reason.
However, it is still possible to withdraw a bid under certain circumstances. Specifically, you will be permitted to retract a bid as long as the item has not yet been announced as “sold” and the hammer has not yet fallen.
If the auction ends within 12 hours and has bids, you cannot end the listing early. If the listing ends in more than 12 hours, you can cancel the bids and then remove the listing.
Buyers can request a cancellation, but it's up to the seller to accept or decline the request. If multiple items were purchased as part of the same order, then all items in the order will be cancelled. An order cannot be cancelled if: The seller has dispatched the item or the item has been collected in person.
