Thanks, Lkorrow. But I have one or more of almost everything you mentioned. This conversation was originally about wealth preservation - the chief reason I have over 40 guns. There aren't too many other things I can sink a lot of my money into with confidence that they'll keep their value down the road. Farmland, PM, guns, ammo, alcohol and small businesses (owning one, not buying stock in one) are about the only items I've been able to think of. Other things are hard to store or trade, for one reason or another.
The topic of buying to survive a post-TEOTWAWKI world is a good one too, but it's a considerably different topic. It leads to the discussions of things to buy, but not things to buy IN BULK.
I think that is the direction you started steering this conversation. The list of things to buy, things to do and skills to learn for surviving TEOTWAWKI is INCREDIBLY long. But while there are an enormous number of things we would need to have, in most cases we'd only want to have two or three of them, not dozens, and not tens of thousands of dollars worth.
