This is something I plan to start prepping for soon. I've heard a few thing that seem feasible and make sense like storing pot & tobacco seeds for growing after the SHTF. but I'd like to here what you all are doing.
Hard Alcohol is definitely a great barter. I have 3 cases of vodka stored now, but that's for personal consumption. Maybe I will store more for bartering purposes.I was considering buying and storing hard alcohol (because people want to wash away their troubles).
It also makes for easier bartering negotiations...
