Amazon Data Stream
(This script was previously known as the Amazon PHP Product Feed) This free (under the GPL) script provides a real-time, searchable Amazon.com catalog. This script enables visitors to purchase Amazon.com products allowing the website to obtain a commission from each sale. Setup is now easier than ever and visitors may choose to purchase 3rdparty new and used items (with no extra work from you). This new version is almost completely template based and is more search engine friendly than ever.
