Please leave a comment stating your location (City), which stores in your area double coupons, and what is their policy regarding such (i.e. how much do they double, are there item limits, coupon limits, etc.) I will list the information you provide as a database to assist other shoppers.
Note that I am not personally guaranteeing any information shared here. However, because store policies seem to be constantly evolving, I find that I can’t always rely on what I read online. This will provide some real-time insight from shoppers who actually patronize these locations.
No known doublers except for the occasional KMart promo. –Thanks Linds!
