Could be an interesting marketing exercise, though. Even if you don't receive the product in question, you may end up wanting to buy one for yourself anyway.
Also, the 4-step diagram showing people 'how it works' has two steps saying how one signs up, one saying 'Beg & Vote' and then 'WINNING!'. It doesn't explain that well what the site's actually about. Something like "Tell us why you should get this prize","Vote for other users", "Win!" could work better.
Or I might be wrong. I guess feedback is (usually) better than silence, so there you go. :)
EDIT: Aesthetically, the site looks really nice. The scrolling sidebar's annoying, though. Using the scrollwheel or scrollbar makes it lag behind. It distracts from the items on show, which should probably be the focus of the user's attention.
