I've been looking at affiliate AHBAL for a while and when the AppSumo deal came up, I just couldn't resist.

This lifetime deal has saved me from paying $5 a month for Genius Links in perpetuity. It also allows me to have more visually interesting ways to present the product which will no doubt lead to higher conversions.

I'm in the process of migrating from Genius Link now. Sadly, there's no way to migrate other than manually, but it's relatively straight forward to do so. No complaints from me here.

Highly recommended for anybody running an affiliate site.
