A new MagicBand On Demand kiosk is now available at the recently opened The NBA Store in Disney Springs, according to Blog Mickey. The NBA Store is part of the new The NBA Experience attraction opening in about a month. Looking at the pictures, it appears that there is at least one new MagicBand design for every NBA team logo, which is 30 teams currently.
