No, and I've been curious about them. I think the key is the purchase reimbursement, and as you know, some are higher than others. There was a location just a few blocks away from where I live, and i was considering checking it out, just to kind of test the waters on the shop. However, even though I have never been in that particular store, I really cannot imagine being able to purchase something there for the reimbursement amount.
The different types of businesses involved in the shop is pretty nuts -- incredibly diverse!
