This month at Walgreens, spend $10.00 on Listerine dental products and earn 5,000 Balance Rewards Points at checkout. The 5,000 Points are worth $5.00 when later redeemed for store credit. Reach $10.00 before submitting manufacturer coupons to earn those Points. Buy three Listerine floss packs and use three different Listerine coupons. (Each has a limit of one per person.) The final price is $0.99 each!
