You can also check out survival blog.com. Lots of good info there.
Personally, I wouldn’t do kits. I would do bulk foods to be able to better make up my own meal plans.
frugalsquirrels.com forum is an old Christian based prepper forum and while membership has gone way down due to people going gray man, it’s still a good resource. There’s one massive thread called “Think you can’t afford to prep? Think again.”
It’s the ultimate, how to prep affordably guide, and not buy those pre-packaged kits. As for kits and bulk food, this outfit in Utah HAD historically been one of the best, if for no other reason than their flat rate shipping rates. https://www.beprepared.com/pages/shipping-rates. Looks like they have strictly #10 cans now and not very cheap.
Plenty of info out there on using 5 gallon buckets with mylar bags and O2 absorbers to store dry goods. Sometimes, desiccant is needed instead of O2 absorbers. I have a 4 gallon bucket of salt that is a solid block because I used neither. I could chip and scrape some off if need be. The #10 cans would be fine for dried fruits. Freeze dried anything lasts many years. That’s why instant coffee stores longer than ground of even coffee beans.
I’m lucky to have Amish and Mennonite stores not too far from me that carry 50lb sacks of grains, salt, sugar, beans etc. I don’t prep like I used to since I left the East coast and moved to rural MO. I’ve been learning to garden and will be planting fruit/nut trees over the next few years and much of it will be improved varieties of what already grows here wild.
I’ve already bugged out and am at my retreat so to speak.
