Wait for sales wherever you buy! Augason.com has one sale product every day. Good way to go if buying a case (not a minimum purchase, but cases of stuff like biscuit, pancakes, veggies, etc).
Prices have gone up over the last couple of years. Full price is pure price gouging...with freeze dried meats being at the tip-top of the scale.
Costco, BJs Warehouse, Sam’s and Wal-Mart offer dehydrated and freeze dried foods. They sell a lot of Augason. You might have to buy online thru them.
RE meat. If you’ll rotate...buy canned meats by the case online. Not cheap, but cheaper than freeze dried. Canned meats don’t have the 25 year shelf life of F.D., but if you’re rotating stock, you’ll be good. Canned beef, hamburger, pork, chicken...they’re not bad.
Buy a good 20+ quart pressure cooker and lots of pint and quart jars. Can whatever you can grow or buy cheaply. Secret is to make things you’d eat anyway and keep the supply fresh.
