Creates blog posts from Amazon.com search results. Requires an AWS key pair (obtain from https://affiliate-program.amazon.com/gp/advertising/api/detail/main.html). Has the ability to search any index for the given search keywords and add a blog post for each of the results. 
Can customize:

The styles of the post are hard coded as of now. I’ll add a separate css for the styling of each of the elements when I get some time. To add affiliate tags to links to Amazon. please use the Amazon Affiliate Link Localizer plugin.
