Revising or Terminating an Auction
You may revise your listing after it is posted, depending on what type of listing it is — auction, fixed-price, or store — and how much time has passed since it was originally listed. Check eBay rules for revisions before attempting any changes. eBay also has rules for ending a listing prior to the scheduled end date. You can end it in this manner if the item is no longer available for sale, there was an error in the starting price or reserve amount, there was an error in the listing, or the item was lost or broken.
