I recall a freeper a while ago mentioning whiskey as a barter item. It does have a long shelf life.
Listerine ?
Whiskey would be good. I would think that getting several cases of those little hotel-room sized bottles of a widely recognized and desirable brand of any alcoholic beverage would be a great way to go. Say, 1,000 little bottles of Smirnov or Stolichnaya vodka. That would be perfect. It will last for years, is of standard intrinsic value, easily concealed, easily transported, always in demand. I would say don’t get the big bottles like five gallons of Kirkland vodka at Costco - too hard to trade. Far better to have in that situation 100 dollar bills than a single Ben Franklin. Get a whole bunch of the little ones instead. They’ll be as good as gold.
Not in my house.
Not in My house. I’d have to hide it really well or someone would drink it all before I had a chance to barter it.
