When is my offer or accept binding?

Once you have made an offer for one or more items, you are bound by the offer as soon as the seller accepts. Therefore, do not make offers for items if you are not quite sure that you want the item, and always make sure to arrange the pickup, if the transaction is with private pickup. This way, you ensure a good experience for both you and the seller.

If you regret an offer you can always withdraw as long as the seller has not yet accepted the offer.

The rules apply to the seller as well. If the seller has accepted the buyer's offer, then the agreement is binding the seller cannot offer the item to another buyer instead.
