Focus on the three basics:
Beans,
Band-aides, and
Bullets.
The basics in each like:
Beans, rice, clean water (Filtration and containers to contain water), seeds, bartering items for food, matches or
lighters, etc
Basic medical supplies, extra prescription items if the family needs them, feminine supplies, books like "Where
there is no Doctor, etc
Actual bullets for barter, weapons do not have to be a firearm, 2 way communication, short wave receivers,
batteries, cross bow, etc.
The secret is to leave them wanting more, e.g. getting invited back to talk about each category in more depth.
The most important thing...Is to have fun
