I have one and it applies to anything that is not purchased with a coupon. I got a vendor's license to do some craft shows and inquired how it would work at JoAnn's. When I purchase fabric or thread (anything that was part of something I'd be selling) I don't pay sales tax. Except, now I have to collect sales tax and send it to the government. I guess I'll never quite get how that's supposed to benefit the small business person! Anyway, when I was inquiring how that worked, the JoAnn's manager gave me the card. It all helps!
