Also, make up and housewares. I’ve personally been pitched ultra expensive titanium cookware in an in-home demo, where they tried to index the price of a pan to that of re-modeling your kitchen. But the company is an MLM, selling “health and nutrition” (actually, incredibly overpriced pans, as in $1000 dollar pans, to people who can’t afford them). And that was a relatively “legit” MLM :-/
Almost all of them tend to have their associates loading up on inventory to make their quota, inventory they will never be able to sell.
