I've been using QuickSnipe from the beginning, and have saved probably hundreds of dollars by being patient and not getting into bidding wars. Of course there are times that the oither bidder has out bid me, but then most of the time they are paying more than I'm willing to pay. In those cases, the bid group comes in very handy. It seems there are invariably auctions that will get ignored. When that happens, I get my item for a steal. All in all, love this service.
PS, please don't tell everyone about it... I'll lose my edge
