Shopping for Dog Food for Large Breed Kennel?

I am looking for high quality, dry, large breed, non-grain dog food in bulk or large quantities. I want it delivered on a regular basis. I have been looking, but don't want to pay 48.00 a bag for a small 40 lb bag. I am trying to find it closer to $1.00 a lb. I feed chicken at .29 cents a pound, but need kibble also.
