we charge $4. 00 a lb, so a 10-lb bottle is $40. 00 plus tax. as a side note, about a year or two i had local collage kids coming in to fill a nitrous bollte enery friday & saturday. this went on for 2 months, (not to stereo-type, but these kids could care less about cars, looked more like skaters or such) so one time they came in and i asked them "so , how do you filter the sulfer out before you inhale. he looked at me like OH **** were caught. i said i could care less as for what you are doing with it. he said that they take a water bottle (like one a company delivers for your water cooler) and cut a hole in the top of it below the neck, put a ballon over the neck,take the hose from the NOS bottle, insert it in the hole to the bottom of the bottle, turn on the nitrous, the water in the bottle filters out the sulfer, pure nitrous goes into the ballon, and the party starts. glad to see what us parents pay for our kids to go to collage is paying off... ...
