In Canada Toronto i my veto lc at WWG or carrier supplier (samething different store i guess) Masters or Eastern refrigeration. but it might be different in the states. they are always in stock. unfortunetly i dont see a lot of guys using the pouch. thats too bad.
Best thing to do. is the order it online. thats the best option. or get it thru a supplier and have them order it for u. its usually in in a few days its worth it tho. im on the veto train now. full speed ahead (-:
