As a normal affiliate you would signup to an affiliate program such as with ebay and then promote the link they give you on your own website. When someone clicks on the link and goes through to ebay- a cookie is put onto their system to track them and if they purchase something you earn a little bit of money.

However when you’re cooking stuffing you don’t actually send visitors to ebay, you simply force the cookie onto their system in the background without them ever knowing. This means you don’t have to drive traffic to them or give them any kind of promotion at all. And because ebay is so big, the chances are a lot of your visitors are going to buy something from them at some point anyway
