There is no Kmart Coupon Policy that you can print out and take with you to the store, unfortunately. There are, however, some guidelines that you can rely on to make your couponing experience easier at Kmart!
Kmart will take any coupons that have a scannable barcode and do not cause an error at the register. This includes coupons for Buy 1, Get 1 Free item, but coupon for $5 or more will not double at the double coupon events. Generally, they will not accept coupons whose value exceeds 75% of the item, but you should check with your store on their coupon acceptance. You will not be able to receive cash back for items whose coupon value exceeds the price of the item.
Another important point is that they will not stack coupons, so you cannot use a Kmart Coupon and a Manufacturer’s Coupon on one item.
Occasionally, Kmart has Double Coupon promotions and during these events they will allow you to double up to 10 coupons and only 1 coupon will be doubles per item.
I recommend becoming a Kmart Member because they give out nice benefits and occasionally gift cards for certain purchases!
