TemplateMonster offer an affiliate program were you can sell there templates and make a commission of every sale. The only problem is they only supply a simply javascript link to display a list of predefined templates on your wite. This is extremely limited and not very good for search engines or non-javascript browsers. We have developed a PHP script that makes use of the API available from them, making the display of the products far better and much more search engine friendly. The script is totally free to use.
