I want a link on my Web site that sends the user to the Amazon homepage, but includes my affiliate code so that any subsequent purchases get credited to my account. I have been browsing through the Amazon Associates portal and there only seems to be a way to link to a specific product.

I found this link on daringfireball.net:

http://www.amazon.com/exec/obidos/redirect?tag=daringfirebal-20&path=subst/home/home.html 

If I replace his affiliate code (daringfirebal-20) with mine, will this work? is this documented anywhere?
