I actually have one of these coupons and tried to use it at Target. The most they would give me was $3 something so I didnt' use it. If anyone has had luck using one please let me know where so I can get the best deal with it.
I've used 2 of them already at Walmart on huge boxes of cat litter. It scanned and everything was fine. I don't know why Target would only give you $3.
