mx123.com any good?

I've checked out the prices on mx123.com for xbox 360 games, and they are unbelievably low. Has anyone had any experience with this site? Scam?

thanks

Here is the whois info on that site.Actually looks like they own 2 sites or has 2 emails. Hope it helps. All I see on the site is prices they pay to buy your used or new games. Seen no sales for any??

actually I think that this site only buy games, that is why the price is so low, the buy the game at that price!
