I have an empty that I would like to refill. If you develop a refill plan, please let me know.
I do not think USPS will allow compressed gas cylinders to be mailed; however, I believe UPS will transport them. I kind of speak from experience as last year I purchased a ten-pound CO2 extinguisher from a fellow on the East Coast. It made it all the way across the country until the UPS man dropped it on my porch. When I opened the door the valve was sticking out of the carton and heavily coated with dry ice. The sender had shipped it in a large carton filled with styrofoam peanuts
