I used to work for an auctioneer years ago, and all I had to do was spot paid bidders, and escort them out the door. If the only real source of revenue for a company that reverse bids is from the cost of placing the bid, I would seriously doubt their validity. I'm with WF 110% on this one. Just the thought of potentially being able to buy something for the cost of shipping is enough to make me question the whole operation.
