When you go to CVS to pick up all of your free stuff this week, stop by the pharmacy first. When you ask the pharmacist about the “auto-fill” program they will give you a booklet with information and another booklet full of coupons. The coupon book has various coupons in it, but also includes 2 $4/$20 coupons good for several months.
(Sorry for the blurry picture. I was being bumped by a baby who wanted to tear this to shreds. That’s what happened to my other one! This was the best picture I could get considering.)
