update: The discount offer is over. You can still buy the Affiliate Ninja product though – while the discount was great I do think it’s a tool worth investing in if you do affiliate marketing.
The plugin allows you to manage affiliate links on your blog in a way that I’ve not seen done in any other tool in the back end of your WP blog.
If you’ve been meaning to check it out – you’ve got around 24 hours to do so (as of the time this post goes live).
