Cheapest place to buy chips?

whats the cheapest place online or near chicago area to buy clay chips?

Those are not clay chips. They are plastic with a piece metal on the inside.

Nothing wrong with those type of chips, just don't let anyone tell you they are clay.

how are they not clay?

They are not made of clay. They are made of plastic with a metal insert to give them weight.

Very few chips made today are clay (too costly).

For more information on the subject, go to pokerchips.com. That site has (or at least used to have) a description of the different types of chips (plastic, clay-filled, composite, etc.) available these days.
