once someone places a bid I no longer have the option to end it or to let someone use GIN. I'm sure if you can wait and bid on it that you can win with less credits though. good luck
As my very first auction is coming to an end I just wanted to thank every who bid. Good luck to those of you still in it, as we approach crunch time. I've also but up a 2 day xbl trial if you're interested in that as well!
