One guy in Austin was into Amway; if a person didn't want to sell the stuff (so he got a comission off their sales) he would pressure them something fierce to place an order from him. I'm sure they were fine products, but he was really annoying about it.
The sisters had needlepoint-kits parties, tupperware parties, and this one brand of makeup I can't recall the name of.
Up North, a pal of mine did, in the space of three years: financial management, Klamath blue-green algae, and Melaleuca (stuff made with tea-tree oil.) I even got talked into being a Melaleuca agent, although I never ended up selling it to anyone but myself. Turns out, nearly every sis in the hall was shilling Mela's products, and the one who was above us all in the scheme was the p.o.'s wife; she got pretty mad at me when I ceased to be her agent, and ended up coming to where I worked(!) to try and wheedle me back in.
I was never into trying to sell stuff to my friends, as it struck me as being sort of tacky.
