On February 8, 2011 I traveled to Walmart to get my dog some treats, and I had a $2.00 coupon for Dentastyx from the manufactorer. When I went to check out the coupon would not scan, the expire date was 3/18/11, the cashier tried two more times and then called over the manager. She came over (her name I didn't see on her badge) and she read the coupon. Then she told me the picture on the coupon says 7 stix, and since I had an 18 stix bag they wouldn't take it. I even showed her where it stated Available in Mini, Small/Medium and Large, and she still wouldn't take it. This isn't the first time coupons have not rang up on your registers and they were denied, is your policy only to take certain coupons and not all that are brought in. If you do not want to honor any coupons, why don't you post no coupons on front of your cash registers.
