Dont know if anyone else has posted about this, but I recently purchased a 1.25 gallon bottle of
Meguiars Gold Class Car Wash Shampoo at Costco for $7.49. That's about 1/3 larger than the $8.49 bottle at WalMart. It's an automatic manufacturers coupon good until June. Awesome deal for amateur detailers like me! Just wanted to let you guys know.
