Earlier this week we wrote about Halls Cough Drops for $1.00 at Rite Aid. Well, the deal just got better! This morning a new $1.00/2 Checkout 51 rebate became available. Purchase two bags of Halls Cough Drops which are on sale, two for $4.00. Stack a $1.00/2 Smart Source coupon with a $1.00/1 Rite Aid store coupon. Pay $2.00 out of pocket and submit for the new Checkout 51 rebate. The final price is $0.50 per bag!
