There is a nice new $1 off Listerine printable available. We will also be getting a $2 off Walgreens store coupon in the Walgreens ad this weekend, so it should make for a pretty decent deal when you pair them up.
Here is what your scenario will look like:
Walgreens in-ad coupon for $2 off Select Bottles of Listerine
-$1 Listerine Coupon
=$3 off One Bottle!
It is a good idea to select another coupon or two to print along with this one to prevent an ad from printing after the coupon.
