I saw the coupon offer on the bottom of a previous register receipt. I thought if I bought $20 worth of stuff that I would get $4 off right away. After I purchased the items I handed the $4 off offer from the bottom of the previous receipt thinking I would get $4 dollars off. At that time the clerk said you have to apply online but never said anything about having previously signed up inorder to get the coupon. The whole offer is ridiculous and very misleading.
