PHP/mySQL-based Affiliate program

[markbm]

I am interested in implementing an affiliate program (% per sale) on my website and was wondering if anyone had any suggestions for an easy to implement / relatively low cost solution.

I have already been to the http://www.php-affiliate.com website and registered to check out their offering but have not been given a username/password to access the material, and its been over a week?!?!?!

Any ideas would be greatly appreciated. Thanks.

I've got an old pay-per-click system that I wrote a while ago - if you can supply details of the e-commerce solution you want to integrate it with (and possibly examples?) maybe that can be used as a basis for what you're looking for?
