I have only found them on-line at those places, not in store. If you have a restaurant supply store in your area they may have #10 cans of fruits, veggies in water/juice pack, but not dehydrated (at least in my area that is all they have). I have heard good things about Honeyville grains, you can google them. Hopefully someone with more knowledge then I have will be along to give you more information.I haven't seen any here in my area but I have seen posts on other boards that Costco, Sam's Club and Wal-Mart are selling some freeze-dried stuff at certain locations. You might "google" and see what you can find out there.
Sorry I can't be more help.
