I have my tanks filled at Ace Hardware for a flat $14.99. They put it on
a scale that tells them when the weight is right, but there is also a
gauge that you can watch to see exactly how many gallons they put in. I
suppose if you took in a partly filled tank you'd end up on the losing
side, but I only fill completely empty tanks, and they put the full 5
gallons in.


Some states are making the flat price illegal for that reason.
