These guys opened about a year or so ago, and seems to always have cars parked in the lot. I see them in the valupak sometimes and other local coupon distributors. May be worth checking out how they do things on their website. Maybe a good comparison if you wanted to open a place away from your residence. Here's a shot of the shop, it's pretty small.
