Availability
Best Offer is available for listings using the fixed price and Classified Ad formats, and in eBay Motors. Best Offer isn't available for auction-style listings.
Best Offer isn't available in every category. If Best Offer isn't shown as an option when you list your item, it isn't available in the category you've chosen for your item.
For eBay Motors, Best Offer option is available for fixed price listings and Local Market listings (for dealership subscribers only).
You can't include contact information such as an email address, phone number, or URL in a Best Offer response. You also shouldn't respond to a buyer with an offer to purchase an item outside of eBay. Doing so violates our offers to buy or sell outside of eBay policy.
How does Best Offer work?
If you are selling an item with a fixed price, you can choose the Best Offer option when you list your item for sale on eBay. With Best Offer, you give buyers a chance to negotiate the price with you. Each Best Offer is good for up to 48 hours. A Best Offer is binding, just like any other bid. There is no charge to use Best Offer.
After you receive a Best Offer, you can choose to
Accept the Best Offer and end the listing.
Decline the Best Offer. You can explain your reasons to the buyer if you want to.
Respond with a counteroffer. If the buyer doesn't respond within a reasonable amount of time, you can let the counteroffer expire.
Let the offer expire after 48 hours or when the listing ends, whichever comes first.
