Mention MLM at a business gathering and you are linkely to get all sorts of responses from favorable to down right nasty. Personally I have always had a dislike of MLM. I don't really know why but probably due to the fact there have been so many scams out there that I usually just tune out when someone mentions MLM.
A friend called the other day and asked me to join a diamond club. For $300 I would get a sapphire and then when I cycle out I would get a diamond and $10k. Not a bad return...
