Not sure which claysmith blanks you're referring to, but affordable is a tricky word. Gear (referred to, above) is the go-to guy around here for poker chip lables. He does high quality custom work. His cheapest labels are 10 cents each, so 20 cents per chip. If you're putting them on clay paulson chips that cost a buck or two apiece, that's pretty affordable. If you're putting them on plastic chips that cost twenty cents apiece, that's maybe not so affordable.
But no, I'm not aware of anybody who sells stock poker chip labels.
