I verified that we can use RRs for the couponing doubler event. Since they’re all manufacturer coupons, it would be a no-brainer for me, but just so you’re prepared, some cashiers might refuse it on the grounds that it’s a Walgreens coupon and as a store coupon, would not be accepted for doubling. They’d be wrong, but I choose to pick and fight my own battles. I would wait until the last day to use these anyway, because I don’t think it’s a very good use of an RR, unless you’re buying something that you normally can’t afford for which there isn’t a coupon.
In that case, you’re brilliant, dahling!
