2 good examples to use affiliate links

* Example 1:

Suppose your E-book contains tips and recipes to make better
cakes. Your book will cater to people who like to cook, so you
can include a link to a bookstore that sells cooking books, or
a company that sells cooking material.

* Example 2:

If your E-book contains tips about web site promotion, you can
include an affiliate link for a search engine submission service, or
my "Web Site and E-zine Promotion Made Easy!" book... :-)

Remember; your E-book or report should help your readers, not
rob the money out of their pocket!
