Thanks for the post! Actually, the whole e-commerce development is based on affiliate programs. Amazon has a prolific affiliate program. The Amazon affiliate program gives the person sharing a link a commission not only if the item linked is purchased, but also any purchases made on Amazon during that session after having clicked the affiliate link. You can check this out: http://www.above1.com . It should help. Good luck!
Aff programs are great but man they require more then a year for any decent income or more. If you can’t get traffic none of these online stuff works. Aff programs are awesome if you have traffic though. If you are just starting out then know this is hard work. SUPER HARD! They way Google is doing things (SEO wise) makes it even harder.
