Let's say that my referral/associates tag on Amazon was xxx. If I were to link to a book I would setup a book link with the book's ISBN/ASIN etc. and then also add ?tag=xxx on the URL. This works.
Now let's say that I want to setup a generic link that goes to Amazon's home page. I have tried doing (http://) amazon.com/?tag=xxx but that doesn't work. (Link intentionally malformed so that it's not clickable).
How do I setup an associates link to the Amazon home page?
