Grr!!!!! I've never had this happen before. The shelf price and the price at the register were different (just guess which was higher). I didn't notice this until I got home. I then drove back to Shoprite with my receipt and a chip on my shoulder. I got reimbursed the difference, but what a pain in the neck!
Add to that the fact that I bought the same product last week, cant find my receipt, and Im sure I was overcharged then as well.
