Retracting a Best Offer
When you make a Best Offer or a counteroffer, you're agreeing to buy the item at that price if the seller accepts. However, if you've made a mistake when making an offer or a counteroffer, you can retract or cancel it in certain circumstances.
You can retract an offer if:
- There are 12 hours or more left before the listing ends
- You placed your most recent offer less than an hour ago
You won’t be able to retract your offer if:
- The listing ends in less than 12 hours and it's been more than an hour since you placed your most recent offer
- The seller has already accepted or declined your offer, or sent you a counteroffer
- You’ve already made 5 offers in a specific category
If you’re using the eBay desktop site, here’s how to retract a Best Offer or a counteroffer if it meets the requirements above:
- Go to Bids/Offers in My eBay.
- Find the offer you’d like to retract.
- Select Review offer, then select Retract offer.
You can also retract your offer on the item page by selecting Review offer and then Retract offer. If you’re using a mobile browser or the eBay app, go to the Best Offer cancellation form to retract your offer.
