These companies are all very different, some are true MLMs, others are more similar to pyramid schemes.
I like pampered chef.
I've got a few of their products, and I really like them. They're not cheap, but the equivalent quality product costs pretty much the same in the Department stores like John Lewis.
I bought some alternative products for less elsewhere, and I have to say, I haven't been too impressed. They work, but not quite as well.
I don't sell it, though. I've been to 2 parties, and there are a few other things I'd like from the range so will buy a few bits and pieces every now and then.
But they seem more like a product company, so a true MLM, rather than a pyramid scheme.
Amway, from years ago, I was inflicted to loads of their sessions via family and friends, to become a distributor and earn squillions. But there weren't really sessions to tell me about the products - although they did make an attempt to get their make up out there, packaged not dissimilarly to avon's.
Usborne books, the books aren't bad. But I usually buy them direct from the website, sometimes from fairs.
I quite like Phoenix cards, have been tempted to hold a coffee morning with their cards because I quite like buying up a bulk amount of cards and using them as I need, and I have always liked their cards when I see them at craft fairs, and they're quite reasonably priced.
But the FL and Herbalife ones.... noooooo, far too much like pyramid schemes.
Anyone that tells me about it just to make me a seller, they've lost my interest.
If the product is good enough to stand on its own, and reasonably priced enough to make me want to buy it without being a distributor, then go ahead and talk to me, I am far more likely to be interested.
