Are you kidding? those things are a pain in the but to do. You need to complete some of the offers then get people to join and complete the offers as well
They do work and you do get your products but after all the time and hassle it's not worth it. You have to keep up on the people you got to sign up and make sure they complete their things as well. Total waste of time and effort. Just go out and buy one if you can find it.
There are few actual decent ones out there, they are all mimics of each other now, it's getting rediculous how desperate companies are to get people to try their products.
