Are these guys legitimate?

The prices are way better than GNC has for No-Xplode and Syntha-6. They claim to not allow returns so that everyone gets new products and never a returned product, http://www.evitaminworld.com. They dont have a telephone number but I have been researching them on the internet, BBB and other sources, nothing found as far as compalints. I did notice that they had a banner for Iceman-RX, and that clicking on that took me to the Amazon page where I can register for the Hummer sweepstakes. Their logo is also on the icemanrx.com website as a sponsor of the event which makes me thing this is a legitimate site?
