I have no idea how to discard bids. However, usually people wait until toward the end of the auction to place their bids. If on the off chance you are to win the auction, just put in a request for a refund and we will promply accept so you get your credits back as soon as possible. Too bad though.... its a nice shirt.
If there is a way of dicarding bids, I dont know how to do it. Usually more people bid as the auction comes closer to closing. If for some reason you are the winner of the auction, just put up a request for a refund of credits stating that you are no longer wanting the item. I will be glad to respond immediately so you get the credits back in a short amount of time. Too bad though... its a nice shirt.
