When it really happens: SHTF...

I have always heard the four things to have in a dystopic situation are toilet paper, Jack Daniels, tobacco and ammo not in any particular order.
Barter items I suppose. Lets pray it does not come to that.

You could add a few chickens to the list (live ones).

My family found that during WW2 people will take hen's eggs as "payment in kind", as a "thank-you", as an alternative to cash or if that doesn't work you can give them the entire chicken, dead or alive, which ever they prefer. My father found that he could even "bribe" school teachers with a few hen's eggs, with regards to his school homework or more to the point lack of homework.
