I have a barcode scanner, I have to scan everything I buy, enter the prices and you send over the phone via the scanner they send you. In exchange, you get points, which can be used to get free merchandise. Not worth it my opinion, since I shop at the commissary a lot. I have to enter each individual price. Imagine doing that for 300 bucks worth of groceries. If I shop at a chain, it reads the prices automatically. Not so bad, but out in town is way too expensive. I can send you an invite for that if you want, just PM me your email address.
