Free Milk?

At Shaws this week they have a catalina (coupon printer that prints coupons when you check out) for free milk, when you buy Kellogs cereal. If you buy 3 boxes, you get 1 milk voucher, 5 boxes is 2 and 7 boxes is 3!! Josh is out doing, Josh Costa things, and then its my turn to go out and find some deals! I'll definitly be posting my deals!
