These type of sites are popping up everywhere! There's another one named haggle. They kinda lure you in by showing you "Dan43 won an iPad for $35" "XYZ won an X-Box 360 for $22". Rare and far and few between. They make their money by having you prebuy bids and hope you will get caught up in the auction adrenaline. If you have the time and money, go for it. But be careful. Dan43 might have won that iPad for 35, but no one says he bid $375 on four other iPads he was trying to win!
