|Ammunition, Matches, Alcohol, Just a few things that you can have on hand to trade with.|
I have started a list of things that I think would be good to have on hand with the idea of trading. You can add your own ideas.
Gasoline and other fuels. If the S##T hits the fan gas will be worth more than gold.
Ammunition. Ammunition is hard to make from scratch so supplies may run short. People will be scared and desperate for ammo.
Alcohol and cigarettes. People have vices. They will trade valuable stuff for a shot of whisky or a few smokes.
Medical Supplies. Any kind of med supplies are valuable. Not just fancy stuff like antibiotics but things like peroxide and rubbing alcohol will be in short supply.
Food. It goes with out saying that food will be a great trade item. Starving people will give anything for a can of beans. I know that sounds harsh and uncaring but it may come to that if you want your family to live.
Matches. Most people don't have a clue how to start a fire. They will figure it out eventually but at first they will be desperate for matches.
Candles. People hate the dark. They get scared and put a greater importance on candles than they may really have.
Books. I know this sounds a bit strange but more and more we rely on the Internet for looking things up. People will want books on things like edible wild plants, medical books, survival skills. That sort of things.
So if you get the chance to pick up some extra stuff for trade I would recommend it. It may just save your life.
