Amazon Search free WordPress plugin

This plugin allows you to link directly to items in your posts using a special tag of the form: [amazon ASIN=0123456789]Fancy Title[/amazon] The plugin lets you set associate IDs for each international amazon server and set one server as the default for your site. It also includes an Amazon Search widget which will search any of the amazon servers and produce search results with direct links to products. It also provides an XSLT file for the amazon server to access, which processes it together with the XML results of the search, and then returns HTML. This saves your server from having to process the XML itself. It uses css to format the search widget and the search results. It will look in its css dir for theme-specific css files too, so if you have one in there called your-theme-name.css, it will include it after default.css. This way you may customize search results for a given theme by dropping in a new css file. So if you allow your users to switch themes, you can include a css file for each one and the search will look correct when it is switched.
