Crest toothpaste is on sale for $2.99 at Walgreens. Buy three tubes and earn a $3.00 Register Reward. Use three $2.00 newspaper coupons at checkout. The sale price, Register Reward, and coupons give you a $0.03 moneymaker!
Note: The coupon reads, "Limit one coupon per PURCHASE," which means one coupon per item purchased. It does NOT mean one coupon per transaction. Make sure that the cashier scans each toothpaste individually instead of scanning one and entering "Quantity: 3" in the register.
