Milk replacer

I check the markets regularly. Last report had milk replacer at .42. Locally it's selling for up to $80 per bag. I've had people price it for me and they only want to knock off 1-2 per bag on 20 pallet per month orders.
I guess what I'm asking is where can I get the replacer bulk before they put in a bag with a label and the raping commences.
20 ton per month I would think would qualify as "bulk". It's be worth the drive but I can find zero information other than what it's selling for in Chicago and what the feed store charges.
