If you got the paper this past weekend, there was a coupon in the RP for $5/2 Tresemme products (x 12/15). Well, if you head over to Wal-Mart, you can score yourself two bottles of Shampoo for FREE. They run $2.48 everyday, so purchase two, use the coupon and pay nothing! There is a limit of 2 like coupons per shopping trip. A shopping trip is actually just another term for transaction, which means each time you check out. So if you have 4 coupons, all you need to do is purchase 4 bottles in one transaction and 4 bottles in another transaction. There's nothing wrong with that.
