$10 off $20 coupon from KMart
Kmart is offering a $10 off $20 purchase coupon that's good until 5-15-10. I don't think this coupon is going to be available much longer because it's limited to the first 40,000 downloads, so hurry and print yours!
***UPDATE (3/19)*** According to Swag Grabber, Kmart is no longer accepting these coupons. WTF? Some of the commenters said they had no problems using it while others said that their stores wouldn't take them. I would call my local store first to make sure.
