Who is PriceGong?
PriceGong is a browser add-in for Internet Explorer, Chrome and Firefox that analyzes web sites your browser visits and attempts to find coupons and other deals associated with the merchant's product offerings or services. If PriceGoing sees a corresponding deal, it will attempt to inject an affiliate 'code' in order to collect various affiliate based commissions if a purchase is made while trying to offer you the best price of that particular product, or, in many cases try and show you an alternative product that is similar even if it is sold by a different merchant.
PriceGong works with third-party content providers to serve comparative offers. They share the information with such companies in order to retrieve and present alternative product pricing and information. PriceGong does not place any restrictions on usage of this anonymous information by its third-party partners.
