I know someone who made money selling Pampered Chef, but it did require a fair amount of her time going away to shows.
CM, I'm not so sure about. I briefly considered it just because I would get a discount on supplies if nothing else, but there is an initial outlay of cash that I didn't want to get into, plus you had to charge for the "shows" unlike Pampered Chef where you attend for free and decide whether or not to buy anything. It's hard to get people to come to your house for a Creative Memories class when they have to pay $10. I figured what was the liklihood of me actually making money when the people who bought CM supplies and went to crops already had a distributor. Several moms in LLL were involved, and on my local lists, so it just seemed like the market in my area was saturated. Plus it seems like it would be fun to host a crop, but you can get together with friends and do that. When you do it through a CM consultant, you have to pay a fee to get a spot at the table, and while I might be willing to do it every once in awhile, I'm not going to do this on a regular basis just because there is a cost involved. I'd rather invite people to my house and tell them to bring snacks if they want and they don't have to pay me.
Of course, at a CM hosted crop, I believe you get to use their supplies like cutting systems as such, so you have access to stuff you may not want to buy. It might be worth it for that. But you pay for any stickers and useable supplies, I believe. I don't quite know, I've never actually been to a workshop like that, although I did host a class in my house once, and I paid the fee for my guests.
I have a friend who sells Avon, and she was sending me e-mail, telling me to get my weekly order in, and it was getting annoying. How often am I going to order stuff from Avon? I was willing to do it once or twice, but the expectation that it would be a weekly thing just irriated me. I guess I worry about that sort of thing with friends, like I'm expected to help them out by buying stuff.
