If I could provide a rating of no stars I would. My son moved from his mobile home in Gouverneur for which MX Fuels was the propane supplier. We knew we'd have to pay a return fee for the gas tanks of $150, but then they charged us a restocking fee of a $1 a gallon which adds up to hundreds of dollars. They in turn will resell that gas for full price. My advice, turn on everything that runs on gas BEFORE you return the tanks.
