Hey there. Welcome to Listia ! Once an auction has been bid on there is nothing a member can only updates no cost changes. I can only hope that it goes for good credits. There is a perk that members can earn , it's called Get IT Now or GIN. The member will put up an amount that they would basically like to get and then if a bidder wants to pay that amount of credits the item is there's as soon as they press the GET IT NOW Icon. If you look into Listia's buying credits system, 1500 credits equal $5.00. So with that in mind you bid what it"s worth to you ! Good Bidding Thanks Kimberly :)
