All Consuming RSS feed and creates an Amazon link to it. If you pass it an associate id, it will build that into the ad too. Once you've activated this plugin, you'll need to stick this code into your template somewhere (probably on the sidebar): <?php allconsuming_amazon('allconsuming-username', 'amazon-associateid', ad-style-number, 'div-css-style'); ?>. Everything except the first parameter ('allconsuming-username') is optional, so you can leave them off if you want. See the plugin file for more info on the other parameters.
