MasterCard Inc. has launched the Priceless Gift Finder to enable cardholders to search for and buy gifts online, the company announced Monday. Online shoppers using the tool can choose a price range and pick the personality type of the gift recipient. The Gift Finder then shows appropriate gift selections and buyer ratings and reviews from Amazon.com. Cardholders can make purchases directly from Amazon through the Gift Finder Web site. The MasterCard Priceless Gift Finder is part of the card company's integrated marketing campaign, which includes a new Priceless television spot and online media banners that launched this week. The TV spot, Web site videos and online banners feature NFL quarterback Peyton Manning and "How I Met Your Mother" TV star Alyson Hannigan.
