Every CO2 supplier we could find in the Phoenix area (Arizona) was checked one by one, and 15 of them made the list. 2 will refill the cylinder you walk in with. 5 only swap it for a different tank, which matters if yours is new or an odd size. 8 would not confirm either way, so those are marked call to confirm rather than guessed at. 5 confirm food grade CO2 for anything you actually drink; the common sizes here are 60L, 10lb, 12-16oz; most cover welding, soda, homebrew.
