I have never made any money through PPC affiliate marketing. That's why I am here. However, I do make some money from Amazon's affiliate program. I run a tech blog and my Amazon income shoots up during the holiday season. Last month I made $688 through Amazon. This month so far, I have made a little over $500 through Amazon.
My full time income is from mobile apps. My iPhone and Android apps do well. I also made good money selling a script last year. The script sales were making me a around $120 a day until I sold its rights to someone.
I program and design my own apps, scripts, and sites.
