This simple plugin will scan your website for links pointing to Amazon marketplace, extract ASIN and check it against Product Advertising API to see if it's still in stock, and can be purchased.. Upload pac php to the wp-content plugins directory. Activate the plugin through 'Plugins WordPress. Navigate to Product Availability > Settings and configure your Amazon Product Avertising API v5 credentials. Click on Scan and Check and wait for the scanner to print out the results of products that are no longer available to buy... On the version the plugin works with links containing the domain and ASIN. The scanner is showing products out of stock but when I follow the link to Amazon I see they are available. In order to check if the plugin reported false positive you should compare ASIN you're linking to, and ASIN displayed on Amazon under Product Details section... Feedback is always welcome, please start in WordPress org plugin support forum... Browse the code, check out SVN repository, or subscribe to the development log by RSS...
