K-mart to double coupons up to $2

Start saving high value coupons. K-mart has tested doubling coupons in different markets. However, they will be offering double coupons at all stores during the week of 11/30 - 12/6. They do not except internet coupons and the limit is 75 coupons per transaction. K-mart will double coupons valued up to $2 (that means a $2 coupon becomes a $4 coupon).
