The SHTF scenarios all mention food, fuel, protection and not in that specific order. We had a posting on TP usage, but none on Soap. I've read that when all facilities go down that most water becomes contaminated. So keeping yourself and utensils clean will lead to your survival. And, if necessary, wound care. I buy any bar soap labeled anti-bacterial and I'm always on the look out for old fashioned lye soap. I'll not barter away ammo or food, but a bar of soap will be a useful commodity.
