There is a great new coupon for $2 off ReNu 12 oz. or larger bottles. Walmart sells a single 12 pz. bottle for $7.98 each everday = $5.98 after coupon.
BUT even better is that is just so happens that Walmart sells the exact thing in a 2-pack for $11.96 normally, but this 2-pack is on a temporary rollback price of $10 for two. With the $2 off Renu coupon, you will pay $8 for two bottles = final is $4 each 12 oz. bottle with Renu coupon and rollback price!
