I've written a blog post about how I made around $1000 - $1500 in a month from doing this method. It is basically providing a simple service: GoDaddy Promo Code List to mass audience then cross promoting them with other related offers. A simple technique but you can get some ideas out of it. Let me know if you have any questions. Thanks. http://www.mulamaker.com/godaddy-promo-code-bait-n-switch-technique/
