Rick,

The dollar type stores have them in a pack of 4 - for a cost of..........you guessed it...$1.00 (or there abouts) prices are subject to change, your mileage may vary, check with your dealer for options...

I distribute cork from a floor covering biz I run outside of this one. A 12x12 piece about 1/8" thick runs about $7. You can vector cut this stuff. As far as the market, it's there but I don't think there's a lot of money in it. I could be wrong though, as I am very new to this biz.
