Walmart offers the Meguiar's Ultimate Waterless Wash & Wax 26-oz. Bottle for $7.42. Opt for in-store pickup to dodge the $5.99 shipping charge. (Amazon charges the same with orders of $25 or more with free shipping via Subscribe & Save.) That's tied with our mention from two weeks ago and the lowest price we could find by $6. One bottle will wash and wax three to five average cars.
