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.
GH Tip: If you've placed a bid then decide you no longer want the item, eBay advises you to contact the seller and ask them to cancel your bid. They are not obliged to do this for you. Be polite and courteous and explain the situation. It might make them willing to reconsider.
Whenever you place a bid, you're agreeing to buy the item if you win the auction. However, in some situations you can retract your bid. Keep in mind that you can't always retract a bid once it's made. Bids on items listed in Trading Cards categories, for example, can't be retracted.
If the listing ends in under 12 hours, you can retract your most recent bid, but only if it's been less than an hour since you placed it. If you are outside that time frame, your best bet is to communicate directly with the seller and persuade them to cancel your bid at their end.
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.
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.
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.
