If you haven't heard, it's another week of Kmart Doubles! Same rules apply so be ready to shop for $25 in merchandise from Grocery, Beauty, and Health. I was all set to pick up super cheap All detergent yesterday only to find an empty shelf! Good job couponers, good job! No worries, ask and you shall receive, a rain check, that is. If you arrive at the store only to find an empty shelf, be sure to head over to customer service for that rain check. And, remember, the double coupon rule limits you to four like products. You can visit Cuckoo for Coupon Deals for a great coupon matchup to help you prepare your shopping list!
