Mercedes over at Common Sense with Money is reporting double coupons at Kmart next week. Go here for the list of stores that have confirmed they are participating. This is a great time to stock up on dog treats for a very low cost. You can only use four of the same coupon and usually it will only double coupons up to 2.00(although one week it was 3.00). I've heard that you can't use internet printed coupons, however, it may be up to your store.
Last time I got beggin strips for .25 a bag and a 5lb bag of Goodlife dog food for 1.99!
