Zbiddy advertises selling items such as iPods for $29. Sure they do... the only catch is that you have to pay 60 cents every time you bid. The way they make their money is capping the bid at $29 and letting everyone bid themselves into an early bankruptcy by clicking the BID button. By the time it's over there will be HUNDREDS of bids for the item at that capped cost and zBiddy makes off with five or six times what an iPod would cost if you went to Best Buy.
One also must look at the inventory of material they sell. Up front they tell you about computers and cameras and consumer electronics but in reality, 90% of what they sell are more bid packages, restaurant cards and other material worth nothing close to the value attached to it. STAY AWAY!
