“Product previews are a portal into Amazon.com – directly on your Web site. When users hover over a preview-enhanced link, a small window appears containing valuable content and information about the product you’re advertising, including an image, new and used price, average customer review and availability. It also gives your visitors the ability to add the item directly to their Amazon.com shopping cart. “
