They have Glycerin as follows:
Quart: $11.00
Gallon: $27.05
They have Propylene Glycol as follows:
Quart: $12.00
Gallon: $20.58
The propylene glycol is much thinner than Glycerin and doesn't gum up the cartridge nearly as bad - *more efficient*. I always thinned glycerin with distilled water. I don't need to thin the PG at all.
They are a US based company - not sure about overseas shipping...
Hope it helps...
