Are you near a railroad yard?? You could get a railcar full, it's 100 tons of coal and would require much more work to move, and store,, but who knows?? it may work for you.
The guy in new britain ct has two giant silos on property right by the railroad.
If you could buy a cheap plot just big enough for three cars, nut, pea, rice 50+ tons each, and broker a deal with csx or norfolk southern then you either have a lifetime supply or a business that would probably pay for your lifetime supply.
I know the nb house hold oil is charging 100 to 150 $ above breaker probably 130 for those volumes around 280/ton and its still 50$ cheaper than bagged.
