I think we're kind of finding out what is valuable...food, water, antibiotics, ammo, and enough cash to pay your bills for awhile. I didn't have to stock up on much of anything, other than I did fill some freezer space with meat just because I had room. We keep a year's supply of paper products on hand and replace what we use, pack by pack as it goes on sale. I could have used another gallon of hand sanitizer, but that is because I gave a bunch away to neighbors, the mail lady and such.
