I too have had bad experience. I had purchased some items and had several coupons. The most expensive item that I wanted the discount on with the coupon, the register didn't pick that up. It took it off a $3.00 item. I didn't realize it until I got in my car and looked at my receipt. I marched back in and went to the customer service desk and explained the situation to the clerk, and she gave me credit for the higher priced item. They worked it out but you really have to check your receipt at the register. They always say the machine picks the item automatically. Well sometimes it doesn't select the item you want so you have to tell them.
