BidRack
Consumer Report

I too was scammed by Bidrack. Not only do they make you give your credit card to get information about the site. They give false values for the items they have for bidding. Ie, the IPAD they say has a value of $799 when the one they gave out was the lowest end model.
They make their money on your ". 01" bids that really cost you 50cents a pop.
They are scammers. Don't fall for it.
