Free toothpaste! This week at CVS, buy select Colgate toothpastes and get them free by stacking a manufacturer coupon and a store coupon. These aren’t the low-end varieties either: Optic White, Total Advanced, 2-in-1 and more. Grab the Procter & Gamble insert coupon and head to CVS. Be sure to scan your extracare card at the CVS extracare coupon center to get the $2.00 coupon that is printing for all shoppers. Stack them together for $3.00 in savings!
