Don't know anything about that company but a quick check of their site revealed this:
Food items are packaged in #10-1 gallon cans, except for "Soups & Sauces" which are packaged #5-1/2 gallon cans.

Those are big cans and the ability to store leftovers will probably be comprimised if you had to start eating from these. Perhaps you should buy a few 1-gallon cans of stuff and see if your family can eat it all in one sitting. If so, the large size won't be a problem.

Don't forget to add seasonings and spices to you stash. EVERYTHING tastes better with some cajun seasonings!

Should we start this over in a new thread with a more appropriate title?
