Zero waste would require him to save the bag (or some other container of his own) and go re-load it from the back of an electric conveyor belt…
We don’t go that far, but we do shop Sams/Costco for things that can work in bulk for us. Not batteries: Their smallest size is a double-lifetime supply. But EVOO, big (plastic) bottles of mixed nuts, a year (or more) worth of vitamins… and at Costco, their loss-leader cooked whole chicken for $4.99 (I think). That one comes with a lot of un-recyclable plastic around it. We just grit our teeth about that part.
