In an email from Jerry W.-
My daughter found out that Wal-Mart is now selling freeze dried bulk foods mostly in #10 cans, and some in what looks like 5 gal buckets. The manufacturing company is from Utah and the web site is http://www.augasonfarms.com/ if you would like to buy directly. Their shipping costs seem to be reasonable. They also say that their food is Non-GMO.
Also I heard Winco is selling the storage oxygen removal packs. But they have been repackaged in smaller containment, so I guess I would need to talk to the warehouse person to see what care was taken when repackaging.
