I say 'make your own'.

For 'shelter in place' we have a 30 day supply in storage.

The dry stuff: Dried beans, peas, flour, and rice. A large stack of 1-2 pound packages of dry whole wheat pasta. 6 two pound cans of coffee, bisquick, ramen noodles....

The heavier stuff: Lots of misc canned tomatoes, soup, spaghetti sauce, green beans, corn, chili beans and great northern beans. A dozen containers of peanut butter, multiple types of canned meat and fish.....

Last: 100 rolls of TP and 100 gal of available water, half of it in 7 gal totes.

We rotate by using it regularly, and replenishing it when it goes on sale. We also keep a large backpack, a rubbermaid tote , and 25 paper grocery bags on the rack.

It's way cheaper and we have and use what we like.
