I just got an email that Kmart is having another Super Doubles event 12/5-12/7, BUT it requires a purchase of $25 in grocery and drug store items. There is a limit of four like items allowed and only five coupons doubled per day. You will have to use your Shop Your Way Rewards card to participate.
If you shop at Kmart regularly and want to pick up some groceries while you’re there, absolutely take part in this event as a bonus! If you aren’t a regular Kmart shopper, I’d skip it.
