If the coupon states manufacturer coupon w/Kmart coupon, you can only use 1. For example there is a coupon book found at Kmart, says save upto $62 in pink and white lettering. All of those are manufacturers coupons. There are $5 off $50 Kmart coupons you get from registering with their site (you print them), you can use that combined with manufacturer coupons. You can also combine manufacturer coupons, with coupons that print from their catalina machine.
