As stated by others, they require that you register and provide credit card information. As you move around the site, you suddenly get "bids" in your account with no authorization. You should immediately protest this since if you use one bid, the $150 charge goes through. In my case, it first showed 0 bids, then 500, then 0 and then 500. I made the mistake of making a few bids because it looks like a bargain, but they keep extending the auction. I logged out since it was obvious that it would be difficult to win and then got an email saying I was being charged. What a scam and their customer service is terrible.
