Bfillmaff is correct. The parent site is
www.pokerchipforum.com
Noodle around the site. there are reviews from yours truly on cards. You cannot beat Jim's sales for quality used (and sometimes MINT) casino chips. The deal he has on the cards is a good one.
Be warned . . . stuff gets scooped up VERY fast in these sales. I would recommend going for the cards only, just so you get your feet wet and see what's what.
I cancelled my first order at one of these sales because, by the time I was ready to check out, the quantities I wanted were no longer available.
