Price!pinx allows shoppers to request price drop alerts for any product on almost any retailer’s website. The free service smoothly integrates into your online shopping experience by using a smart bookmark. On the retailer’s website you click the smart bookmark which automatically records the product information and the price for you. Price!pinx then monitors the price and notifies you about price drops as they happen. This has been added to ShoppingBots Subject Tracer™ Information Blog.
