Every CO2 supplier we could find in the Atlanta area (Georgia) was checked one by one, and 15 of them made the list. 1 will refill the cylinder you walk in with. 4 only swap it for a different tank, which matters if yours is new or an odd size. 10 would not confirm either way, so those are marked call to confirm rather than guessed at. 4 confirm food grade CO2 for anything you actually drink; the common sizes here are 130L, 20lb, 60L; most cover welding, soda, homebrew.
