My wife and I both run seperate network marketing businesses. We were both very much against doing these in the past, but it's simple to do from your computer or phone and usually has a cheap starting cost. You just have to make sure there's a demand for the product and it's actually something that you would be proud to sell. We're not getting rich off of them, but it's an easy $500-$1000 extra a month. My friend that got me into it is making $30k a month!! It can be a great opportunity if you choose the right one.
