You're not even gambling on this site. You're just being duped.
I sat there to watch one of the auctions that had a few seconds left on it to see how high it might go. Now, first know that there is a function called BidButler that allows you to place an automatic bid if you're not the winner up to a certain point (as they have on E-Bay). So, I watched the auction for a Nintendo DS Lite. One user was using the BidButler function, while several more kept jumping in during that extra 15 seconds to up the bid and hopefully win the DS Lite for cheap (at this point, it was only $14 with 15 seconds left on the clock).
Now, consider that the username of the user with the BidButler function activated was named DSLite. One can probably deduce, and if you go on the site and check different products you might be able to confirm, that the people that run the site are also bidding on the products to drive up the price. And going by the rules they've set forth, they can guarantee that they won't be selling any products for less than market price, because if they win the auction all they have to do is not order the item.
This is a complete scam.
