okay so here's what the listia people sent me To do this first visit the auction you want to edit, and you will see an "Edit" button near the top of the page. What information you are able to change on your auction depends on whether there are bids on it or not. Regardless of whether there are bids or not on your auction you are not able to change the original Title, the auction Description, increase the shipping fee, remove images, or change a listing from free shipping to any other form of shipping.
If there are less than 24 hours remaining on your auction you aren't able to make any changes to your auction.
