Diana, a BeCentsAble reader, emailed to say that she contacted Kmart corporate and found out that the Phoenix, Arizona stores will be participating in the next Kmart double coupon days from August 16 to 22. If you would like to contact Kmart to find out if your local store will be participating, you can email help@customerservice.kmart.com or call 1-866-KMART-4U (1-866-562-7848) from 6 a.m. to 12 a.m. (CT) Monday – Sunday. That way, you will have time to gather up the coupons you may want to use. There were a few rules to follow last time Kmart doubled coupons. I assume the rules will remain the same for the next promotion so you may want to check this post out here to start planning your trip now.
