Kelkoo Price Comparison Wordpress Plugin By David Fiske
Display a price comparison box on post pages, with results powered by Kelkoo.
Introduction
Kelkoo runs an affiliate program on the Tradedoubler network. They offer an API which means their price comparison results can be shown on third party websites
This widget combines the two and adds managed price comparison results to your WordPress powered website, letting you earn money from sales via Kelkoo.
Demo
See it in action on a live client site at DSLR: Canon EOS 500D. This client is using the UK version of the Kelkoo API.
Screenshots
This is the settings page where you can change the master settings for the plugin. These determine how the plugin works.

Here is the box added beneath each post admin page where you can specify the category ID and/or search keyword for that post.
Instead of a search term (e.g. iPod) you could use the product ID code from Kelkoo for more accurate results as we have done here:

Here is an example of the price comparison block shown beneath each post to visitors. This particular example showcases the Dyson DC25 using a category ID and product ID.

Notice how if you add logos to the logos folder, they display instead of the text on the right hand side. These results have been ordered by reverse price order as per my settings page. I have also cropped this image as 10 results is quite a long image :-)
