RAMDJM, where were you getting your bottles filled? My friends and I have a fill station, so just curious where you were getting your filled in Calgary.
I was buying nitrous for $7.50-$8.00/lb at Rock Alta Trailers up in Bearspaw. He uses a good scale and only charges what goes in and will not overfill the bottle even if requested.
