Check That Receipt Update

I went back to Wal-Mart last night and ended up getting the same cashier as before. As it turns out I was paying attention, and she did scan my coupons. I had two more Muir Glen Organic Tomato coupons last night, and after she scanned them she checked the register, sure enough they just didn't show up. She said, "I knew I scanned them before!" Even more reason to check your receipts, know exactly how many coupons you use, and what the value of them is.
