This week at Walgreens, packs of Scott Extra Soft Toilet Paper are on sale for $4.99. Redeem a $1.00 Checkout 51 offer for a final price of $3.99, or $0.33 per double roll! The Checkout 51 rebate states that it cannot be combined with coupons, and since it is higher in value than any Scott coupons, get a better deal using the rebate.
