I saw your retract of this question but thought you could use the info anyway. Bids can't be taken away but if you are winning you can notify the seller. Once you win you can dispute the auction and say you don't want the item. Some sellers will just agree relist their items & you will get your credits back. That's what I do. I just relist but the seller doesn't have to do that. They can dispute it hold up your credits & eventually possibly win your credits.
