*UPDATE* In true Kmart fashion, they have already pulled the $10/$20 coupon and deemed it invalid. You may remember that this happened last year with a Sears coupon. It is unfortunate that retailers have not learned to stop using a PDF coupon and to limit the prints!
The original coupon did not have store limitations and it was/is a valid Kmart coupon. Kmart now says that it was suppose to be for only certain markets. I do not know if our local Kmart will honor the coupon or not. I would say, probably not!
