I don’t do this very often, but I’m going to link to another blogger’s post. He has put together a pretty good list of bartering items to have on hand in the event the currency of the realm is no longer any good. The list includes things you’d expect, such as booze and cigarettes, but there are a few other considerations I couldn’t have stated better myself.
Click here to see the post. When you’re finished, close out that window, and you’ll be right back here where you can scroll down the sidebar and look for some of the things you’ll be needing.
