a few things to consider
1) most only will ship a drum to a business address, not home. Mach7 (Morgan) is that way.
2) you have to be able to move a fully loaded 50gal drum from where the truck drops it off to where you are going to store it. got a forklift?
3) you have to pump out 50 gal's into 1 gal containers. otherwise, if you use it straight from the drum, the fuel will absorb alot of moisture as you get low. also alot of wear on your fuel pump unless you get an industrial one.
4) what to do with the drum after it's used up
