Bookaboo finds better prices while you are shopping. It adds a small Prix comparison window to online book stores that displays pricing and availability from numerous competing merchants. Bookaboo automatically searches the Internet for used and new books and gives you an overview of where a book is on stock and at what it costs. bookaboo is not a toolbar that clutters up your screen or "adware" that bugs you with annoying pop-up windows; instead, it works silently in the background while you are shopping and notifies you gently when it has found good offers: a tiny window in th upper left corner of the web page shows you the best offers from book sellers such as Amazon.com, Overstock.com or Walmart, complete with pricing and availability. Bookaboo works with Internet Explorer 5 (or newer versions) and compatible Navigateurs such as Maxthon, AvantBrowser or NetCaptor.
