Both Apple's iTunes store and Starbucks' website have begun selling a $30 (Product) RED virtual gift card that offers $15 in credit at each of the two vendors: $15 to spend at Starbucks, and $15 to spend on the iTunes store. Five percent of the purchase price goes to the Global Fund AIDS research foundation. The credit is good for anything purchasable in a Starbucks, or from the company's online store (US only). The iTunes half can be used to buy music, movies, apps, audiobooks, e-books and Mac App Store software.
