internet affiliate buissness

I've actually been wondering about that question myself. I've started doing some research and got overwhelmed with all that is out there. So many businesses want you to join their organizations for a fee, and everybody under the sun seems to be selling a kit on how it works. My worst fear is getting caught up into a scam site! So I've decided to hit the bookstore and review a few books on the topic. There's just too much on the web for me..If you find out how it works, please share and I'll do the same. thanks
