Something I’ve been thinking about is vacuum packing sacks of Bugle Boy (for those that don’t know it’s loose tobacco in a foil bag with cigarette papers)in canning jars for barter.
Design a battle pack like an MRE, tobacco, papers, matches all in a waterproof sealed pouch, small in size to be considered a monetary amount of an easy transaction.
Say make a three day package, a weeks package.
