  the user to enter the same information all over again. The positive aspect of cookies is that they make it
  possible for users to take advantage of the convenient “shopping cart” feature of many Web sites. Unfortunately,
  cookies also make it possible for marketing organizations to monitor users’ browsing patterns;
  users then find themselves the targets of custom-tailored marketing campaigns.
