David, do they sell to non Mormon?
You can buy canned the dehydrated food without belonging to their church.
If you can put together a group of 5-6 people, you can reserve a spot to
do your own canning. I have done this several times. You give them a list of
the items you want to can and they have the bulk items ready. They supply
the cans, lids, labels, boxes and a couple of people to oversee your group.
Last time I talk to someone doing that, their supplies were getting low. Lots of
this going on around the country. Here is their info
