Another option, if you can legally store it, is the 55 gal drum.

I used to buy kero from the hardware store in the 5 gal jugs. Then the prices started to go throughout the roof, i mean $50 for 5 gal, com'on.

Then I started getting the 55 gal drum delivered to my work. It is WAY cheaper and actually is a lot more convenient.

I have a special room to store it in, but not sure my homeowners insurance would cover me in a fire if I kept it at home.
