Bloggerkit is a little system that help you integrate your Amazon affiliate ads into your blog. You simply activate the ads by writing some keywords in the end of your related blog post. You will (of course) still get paid by Amazon for your affiliate earnings.

You can easily customize the ads to match your blog design. Another good thing is that these ads work with AdSense, as they are not contextual.

Of course there is also some downsides with Bloggerkit, for example:

Only 85% of your own ads will be showed to your visitors. This because Bloggerkit (as a payment for using their services) shows 15% of their very own Amazon affiliate ads. It also seems that the keywords you type in on your blog post appears for your visitors.
