CVS/Pharmacy has apparently changed the packaging on it’s store brand toothpaste. As a result, they have placed the older designed packages on clearance. Some stores have them marked down to only $0.70. When you use the $1.00/1 printable CVS/Pharmacy Store coupon, you can get 2 tubes for $0.40 out of pocket or just $0.20 each.
(Always keep in mind that clearance items may very from store to store, so you may not be able to find this one where you live).
