If you opt out, though, you may still receive generic advertising. If you prefer that we do not use this information, you may opt out of online behavioral advertising. This information may be used to deliver advertising on our Sites and offline (for example, by phone, email and direct mail) that's customized to meet specific interests you may have. Here's how it works: We gather information about your online activities, such as the searches you conduct on our Sites and the pages you visit. Relationship-based ads and online behavioral advertising help us do that. We strive to provide you with information about products and services you might find interesting and useful.
