For larger sizes of PG try Tractor Supply. United States Pharmaceutical (USP) grade intended as medicine for cows About $25 per gallon, which lasts me four years. Possibly longer if you mix with VG. Possibly less if you sub ohm...
Oh, BTW the 'V' in VG is vegetable. Nothing to do with organic. You can buy organic beef, lard, etc if you are so inclined. Glycerin without the 'V' is most likely derived from animal fat.
