In a true SHTF, true, you want unscented shampoo, soap and deodorant. Those will be worth money. imho.
Nah. You want frilly, fruity, candle scented crap if you're going to get rich.
Q: What made men go out and build sky scrapers, suspension bridges, conquer foreign nations, write great literature, form governments, jump out of hot air balloons at the edge of space, fly to the moon, etc?
A: Not wanting to be stuck around the cave fire with a whiny, bitchy woman nagging at him about this and that all day long.
Q: And how does a man make that whiny, bitchy, nagging woman act all happy to see him for like five minutes a week after coming home covered in the entrails of his enemies and smelling of burnt JP-5 and concrete?
A: By giving her frilly, fruity smelling homo shit and sparkly things.
Now imagine a world where women have been accustomed to smelly, fruity smelling crap everyday and suddenly it's GONE. Like forever gone. Imagine how much valuable crap men are going to barter for soap just to shut them the hell up.
Which is why my brother stole my SHTF business plan from me, and now I have to kill him with a funny brake light in the gas tank April Fool's prank. And not in a funny "ha ha" way. More like " Hey dude, why don't run out and get us some beers and when you get back I'll tell you a funny joke."
BOOOOOM!!!
"Funny, huh dude? What's that? You couldn't hear it? Hang on let walk across the street and tell it again in your other ear."
