From time to time, we may use third-party advertising companies to serve ads on our behalf across the Internet. In the course of serving advertisements to this and other sites, these companies usually collect information about your visits to our Web site, and your interaction with our ads. Any information that these third parties collect is completely anonymous, is in a non-personal aggregate format, and is shared for purposes of analysis and improvement of our site. For instance, they may keep track of how many of our ads you had seen before visiting our site. This is primarily accomplished through technology, including cookies and action tags (commonly referred to as Web Beacons or GIF tags), which we will place on various pages within our Web site. These third party advertising companies may, in turn, use information about your visits to this and other Web sites in order to provide ads about goods and services of interest to you. If you would like more information about the practices of our third party advertising contractors, if any, and to know how to contact them to advise them of your choices about not having your information used further, please click here.
