Third party membership programs . We work with certain third party entities to help them administer their own membership or rewards programs by providing them with purchasing information about their customers who make purchase from Barnes & Noble. We disclose only the information that is necessary to make these third party programs work and to support your membership in them. This information usually includes your name and e-mail address as well as the dollar amount of the purchases made at Barnes & Noble. We require such entities to obtain your consent before we provide them with this information, which they usually do as part of their own membership or participation rules.
