Find out from the seller, the dimentions of the package, if the holes are just taped shut. Then ask how much it weighs. Then...call the United States Post Office near you and ask them how much to ship a so and so package from the seller to your home. Then...you have the seller magic marker your address on the tank, and tell them to drop it off at the nearest post office...which, is their back door!!! The Post Office will pick it up.I did this with a lot of stuff from my trip from Cleveland to Miami. I sent everything back in big plastic containers, and duct taped the rims. Came home intact, and cheaper than ANYONE. Even sent an anchor home by mail, a danforth. Just taped the sucker up, added an address, and it came home in one piece!
