This week at Rite Aid, select Crest toothpastes, Oral-B flossers and manual toothbrushes are on sale for $3.50. They are also included in a Plenti Points promotion: buy one and receive 300 Plenti Points. Use a $0.75/1 printable manufacturer coupon and receive 300 Plenti Points, worth $3.00, at checkout. Redeem the Points on a future purchase to lower your out-of-pocket cost. After the sale, coupon and Points, the final price is a $0.25 moneymaker!
Note: I tested this deal and it is not the same Plenti Points promotion as the Crest toothpaste which is priced at $3.00. This means that you can purchase up to two products from each promotion.
