Does anyone shop on these new auction sites?

I guess they've been around for a while but I just heard about these new kinds of sites recently. Like penny auctions and reverse auctions. I'm wondering if anyone has tried them out?

like:

Online Auction, Hottest Products, Online Bargains, Prices Only Go Down at CircusPop.com or
Web hosting, domain name registration and web services by 1&1 Internet

Friend of mine is using Swoopo.com with some success. Tread lightly if you don't know what your doing no deals will be had and you will only further the profit of the site.
