Do you have experience as a rep for products sold at parties (Tupperware, Pampered Chef, PartyLite, etc.)? How did it work for you?

A friend of mine is very successful selling one of these products and I have been toying with the idea of giving it a try. I haven’t been able to bring myself to do it because it is a decent up front investment and I just don’t know if it will generate enough income to make it worth it. Have you ever done this? Were you able to make money at it? How much work did it really take? Please share any experiences that might be helpful!
