This is food for thought. I purchased organic, health food store wheat at well over a dollar a pound. I went to my feed store and purchased wheat for 20 cents a pound. It may require a little extra cleaning, but otherwise is a way to store a lot of wheat for little cash. Since this worked, I decided to check out feed corn. Organic corn, $2 a pound. Feed corn, 10 cents a pound. Again, I had to clean it a bit as I put it into my grinder, but it made great cornbread. It needs to be ground fine because the outer part, the pericarp, will be slightly gritty (crunchy) if ground too coarse.
Both seeds may be planted in your garden also. I now have 500 pounds of wheat and 500 pounds of corn for $150. It can also feed my chickens and goats if needed.
