You still have to find and go through a broker,  He needs his cut!  You have to store it someplace, where is that going to be?  I don't think you will get your best deal in season on the spot market picking up at the terminal (not blended). I could be wrong, you could pick it up today bring it home, leave your machinery sit outside this winter so you can fill your gravel floor metal building with unblended fertilizer, sounds like fun to save a buck or two!
