Head on over to Twitter and “follow” CVS. If you don’t have a Twitter account it’s easy to sign up (and to follow Family Friendly Frugality!)
Click here to be emailed the $4/$20 coupon.
When you make your purchase at CVS, always hand the $x/$xx FIRST. Before coupons, before Extra Care Bucks. If you don’t, you might not be able to use the $x/$xx because your total might fall below the amount needed to use the coupon.
