I have no idea. From what I've read, I can't do GIN option until I've got sellers wings. Let me try to edit the auction to end today with a 2500 credit price. I'll let you know.
Robby, It's not allowed to edit an auction once it has a bid on it. Also, I can't delete the auction once it has a bid. Perhaps you can try to retract your bid.
From what I read, once a bid has been placed, no edits can be made to the original listing such as shortening the auction. I couldn't have used the GIN in the original listing anyway because I don't have sellers wings yet.
