Zpchips.com / It's tempting because they're so cheap, but save yourself the trouble
This whole website looks really shady. There are no reviews anywhere, except these, and they're negative. On Yahoo Answers, there's an obvious attempt to self-promote, when a random person asks about where to buy poker chips and one person with the same writing style answers the question, pretty much sounding like a salesperson I would avoid.
It's tempting because they're so cheap, but save yourself the trouble. I'm sure that if it were legit, there would be many billionaire pokerists right now.
