Consumers now use plastic loyalty cards wherever they shop - including the Internet. For example, Discovery Channel's Discovery Passport™ Card, which is manufactured by Arthur Blank & Company, can be used when making purchases online at Discovery.com, at any Discovery Channel Store, and from the Discovery Channel Catalog. And wherever purchases are made, cardholders build loyalty points toward Passport Reward Certificates and other great prizes. The Discovery Passport Card. It's a multimedia thank-you to valued and loyal customers.
