I was just looking through the Kmart ad, and I noticed they have "super coupons" on the back page. One of the coupons is for All Detergent (50 oz) for $2.97 for "shop your way rewards members only." It is called a "Kmart Savings Coupon." Does anyone know if you can stack a manu coupon on top of this? $1.97 All would be a pretty good deal.
