What is cddvdgametrader.com?

Hi

I have noticed while shopping around the net for used DVD's that a lot
of sellers have an @cddvdgametrader.com email address.
I went to that webpage but can't find how to sign up for this email
service?
They advertise CD's and DVD's but i can't find any DVD's on the site.

Thanks for letting me know

Patrick
