Affiliate Programs/Plugins for WordPresss

Is there an affordable affiliate tool for WordPress?

Hi all, I run a series of web sites built mostly in WordPress and I'm wondering if there's a good application for tracking affiliate referrals and sales directly in WordPress or if anybody can recommend a good PHP script for managing this.

I'm sorry in advanced as I'm sure this has been discussed to death but I've had no luck googling it here and I'm very interested in finding an answer.

Thanks,

Chris

I don't think this has been discussed. If you do a google search on wordpress affiliate plugin you get some interesting results. Some are free, some use a profit sharing model, and some are sold on long sales letters for only $97 if you buy before midnight tonight blah blah blah.

None of them track sales directly in WP as far as I know - how would they do that? Such a plugin would need to be able to log in to your affiliate network and grab your account information, would it not?
