Check out the LDS (latter day saints) for their canneries. Some will sell to the public... others won't. You just have to call around. You can get bulk prices there to beat many other places! I bought whole wheat berries to stock up on for flour/bread later on if needed.
Ramen Noodle soup is extremely cheap and easy to fill a tote with and store in your basement. Would be great barter food! You can fill a large storage tote for only about $30 if you find it on sale! That's a lot of noodles!! LOL
