The list FD'ER gave is really useful.

Most people are stocking up on guns and are totally ignoring not only food but medical supplies as you mention sayitwithamini-14.

A cache of different antibiotics post SHTF of any type will be worth its weight in whatever you want.

Imagine Joe militia guy with 100 AR15s and a 3 y/o daughter with a nasty ear infection. He would probably give you anything for $10 worth of meds.

Or Jane militia girl with a yeast infection. A $10 walmart 1 day treatment will get you anything too (after she's cleaned up of course, LOL).

On top of that is the books and knowledge of what to do with it. PDR, nurses drug reference etc. You don't want to fall into the "a little knowledge can be dangerous" catagory.

Best case is SHTF you can liberate a Dr or a PA and supply him with his needs and use his knowledge in return. I have no problem with sharing my food and supplies with our ER doctors for the years of education and hands on experience they have.

More reason to store lots and lots of food. They will probably also have family they want fed too.
