here in PA< its like 15 bucks for a 100 lbs , or slightly higher pending where your buying from

a few yrs back I had a local farmer that would sell you all you could fit in the back of a pickup truck bed for 100 bucks
MAN was that a steel
would back up under a silo dropper, and he'd let fill till you said STOP LOL

some days I think I left there with about 1800+ lbs of corn for 100 bucks

I used to fill food grade 55 gallon drums and store in my barn
