Check if you have SimplexGrinnell in your neck of the woods. They fill my tanks here in Vegas. Airgas is another place.

Temperature change isn't going to affect weight/mass.

Thanks for all the input. It is exactly what I assumed. I questioned the guy this morning. he had all kinds of excuses. I have found a new supplier. He's a little further away, but for a full tank it's worth it.
Thanks again,

Well, sure, maybe for non-relativistic physics ...

By the way, do places that fill CO2 bottles generally also deal with propane?  Most of the places I see for propane (gas stations, big box stores, grocery stores) all have the Blue Rhino setup and I'd like to see what other options I have.

It would affect pressure which is the real concern with a tank. But still, 2lbs in a 5lb tank would be 60% headspace - overkill. I would think a 5lb tank is certified to hold 5lbs of CO2 and still have space for expansion, but I don't know the specifics of tank certification.
