AdWords & Affiliate Links

Can you plug an affiliate link into an AdWords campaign these days? I've lost touch with their PPC rules and can't find a clear-cut answer in their FAQ.

Thanks.

I'm pretty sure you can. Though I would personally rather send them to my own site where I can capture their details.

Yes you can and you don't have to use aff. in the add anymore.
But they only allow one direct affiliate URL, so one affiliate ad will be displayed.

If there is already an affiliate URL in there, you have to get a higher place.
Either by bidding higher or by getting a higher quality score and CTR.
Otherwise you have to make a landingpage.
