Disney have produced only 5,000 of the MagicBands, which will retails for $29.95 (plus tax). Here's the full details from the official Disney Parks Blog:
As the “Frozen” Summer Fun celebration continues at Disney’s Hollywood Studios, I have some exciting news to share about a new, limited edition retail MagicBand, featuring Olaf from Disney’s “Frozen.” This item is now available at Wandering Oaken’s Trading Post in Disney’s Hollywood Studios. The shop is located between Toy Story Midway Mania and Studio Backlot Tour. I spoke with Kevin-Michael Lezotte, merchandiser for retail MagicBands, about this latest addition.
“We saw a great response from guests when we released two limited edition MagicBands during Star Wars Weekends earlier this year,” explained Kevin-Michael. “This new MagicBand is pre-printed with an image of Olaf ‘chillin’ in summer, and will be presented in a specially designed packaging. These pre-printed MagicBands are another great way guests can show off their Disney Side while visiting Walt Disney World Resort this summer.”
