When I said the location would make it pretty inconvenient to use him for feed, she told me that all I would need to do is call him at the store any time and he would bring my order home with him that night (he does it for a couple of other neighbors of mine - I had no idea).
When I called him to verify all of this (and check prices on what we use) he said since we live so close he'll just bring anything I order right to the house. Then he asked about hay. Turns out he grows/bales hay for his own stock and his store. His prices are about $1-2 a bale less than what I am paying now AND he is willing to sell it to me at the ton price and keep what we don't have room for in his storage barn so that we can pick it up as we need it. I will definitely be going down to look at the hay before I make any commitment on that side of things, but the feed delivery itself makes that part of my life that much less to worry about.
