Coles has Armor All Car Wash Pods (18-pack) down to $5.00 this week, slashed from the regular $22.00, that's $17 off for a product you'd normally have to swing past Repco or Supercheap Auto to find. Each pod is pre-measured and super-concentrated, so one pod does a full car wash without you guessing how much to pour. They use 88% less plastic than a standard bottle of car shampoo, which is a handy bonus if you're already trying to cut down on single-use plastic. Chuck a pack in the trolley while you're doing the weekly shop and you've sorted the weekend driveway wash without a separate trip.
