Starting the week of 12/27, Walgreens will have various Oral-B and Crest products on sale 3/$10 with $5 Register Rewards back when you purchase three. There are also a few coupons to stack for a better deal, so here’s one idea for you:
Buy 3 Crest Pro-Health Rinse 16.9 oz 3/$10
Use 3 $1.50 Crest Mouthwash from 12/13 RP (or $1 Crest Rinse coupon and $2/2 Crest Rinse coupon)
Pay $5.50, Get $5 RR and $.50 Mouthwash from Checkout 51
Final Price: 3 Free!
The Checkout 51 coupon expires on 12/30, so be sure to do this deal before then! Find more Walgreens deals here.
