yeah you can get a little doodad to connect a big refillable canister that you can get refilled locally. you've been soending way too much if you buy any comoany's proprietary consumable accesories.

recently bought a petsafe scoopfree litter box on clearance which has reallu expensice refills because the bottom of the trau is cardboard. i bought a third party stainless steel tray. entirely undermined that business model.

You already bought it yeah. Just switch gas providers and don't buy their flavors.

Also look into refilling it locally much cheaper anyway. Or if not, DrinkMate refills SodaStream canisters too
