I really love this deal on Colgate Mouthwash this week at CVS! Not only is the mouthwash on sale for just $3.50 a bottle, but you’ll get back $2.50 in extrabucks when you buy two. Buy two bottles and use two high-value coupons. Pay just $0.25 each for two bottles. You can get two extrabucks rewards per household for this deal, so if you have four coupons, buy two bottles, use four $2.00 coupons, and get back $5.00 in extrabucks!
