Kmart double coupons

I heard a rumor that Kmart will double coupons from oct 1-5. They are trying it out at stores across the U.S. Utah is not one of the states. But the kmart corp. office says that if you tell the store that you know about the double coupon ad then they will honor it. I am hoping that it is not to good to be true!! I will post my results tomorrow.
