after you get your preps up...

do you plan on stocking any items for trading?
if so what do you plan on buying ?
any items you think are bad for trading? knives,ammo,guns etc

I think some good ideas for trade goods would be:

Mini fishing kits (line,weights,hooks,lures)

Trash bags, bleach, soap, baby food, tyelenol, batteries, cheap flashlights, booze (small cheap bottles), toilet paper.

I wouldn't be opposed to trading guns and ammo under the right circumstances.

I read a post Nuke book where the survivors met on the town green once
a week to barter goods. Something like that, away from my home I would barter arms and ammo for the right deal.
