Cookies are text files saved in your temporary Internet folder that are created to keep track of your browsing history and information. On one hand, this saves you from having to keep entering in your log-in information to view a site. But on the other hand, tracking cookies are used by companies such as Amazon to track your browsing behavior and then make "personalized" recommendations on what to buy from that company. Because this tracking information is not private, one way to prevent this from being known is to delete your Amazon tracking cookies.
