mintina - Listia uses a proxy bidding system. In short, the system bids for you, up to the limit you placed (to make sure you don't spend more credits than you need to win). A bit more info can be found here: http://www.listia.com/about#proxy_bidding
very nice auction...have a 360, but the sound isn't working. and to "johnnyswife", eventually you will probably get outbid...game systems i've noticed since i been on here usually go high at the last minute.
Don't buy from this "creepy guy above" named RockBandGG- He's hardly made any transactions, and has 2 negative feedbacks for not shipping items. One he didn't ship because he said it didn't go for enough credits!
