One guy I used to follow during my ‘gun nut’ phase did just that- he and his partner weren’t mormon, but they have friends that are and that church had days where people could come in and use their industrial packaging equipment, IIRC. (the blog posts where he mentioned this are gone off the internet, although the person in question has a normal blog where he posts about such things.)
From the same guy, I got the impressions that the costco buckets are… not enough for what they are advertised for, and require supplemental food, like meats, and the portion sizes are not enough to provide 2000 calories per person per day. his blog is at least good reading for at least empirical advice on how to set up for disaster scenarios.
Edit: Serves me right for not reading through the entire damn thread before posting. Carry on!
