If you made an offer in error, select the Message Seller button on the listing to provide the seller with some insight and ask that they no longer consider the offer.
Once an offer is submitted, there is no way to cancel or retract it. Prior to making an offer, it's always best to review the listing and Shop Policies thoroughly to make sure you're ready to purchase in the event your offer is accepted.
Keep in mind, offers expire after 24 hours.
