Hi:

When I first started marketing as an affiliate on
Amazon, the Amazon.com site was primarily a seller
of books. So, I showed a few books on my site
that were related to the site's main topic. There
were maybe a half a dozen shown.

For the longest while, I would get sales for one
or two books per month. The revenues were kind of
silly but, it didn't concern me too much because
I thought they added value for the visitor.
