FWIW I made a surprising discovery about Mountain House foods while dinking around on youtube a few days ago. A poster there had a video claiming the cans are actually more expensive than the pouches designed for backpackers. That seemed unlikely to me since bulk is usually cheaper but I hit several sites and crunched the numbers- and he's right! The cans are significantly more expensive per ounce than the pouches for every product I could find.

Now obviously sometimes the cans would still be superior; they do seem to take less space and probably will keep longer. But if you're rotating your stock to keep things fresh the pouches are a better deal (although there's not as much variety). For home use I agree that conventional canned foods should be in mix, too. They're much cheaper and there's more products. Shelf life for canned foods is actually very, very good if you store them properly.
