It’s been out for several weeks now, but Disney’s Frozen is continuing to make even more money on DVD and Blu-Ray, Home Media Magazine reports. The animated phenomenon has topped the charts for eight weeks since it was released on disc in March. Although Frozen topped overall disc sales, the top selling Blu-Ray of the week was actually James Cameron’s Avatar, which has of course been on sale since 2010. Analysts are crediting the surge in profits to a sale that Wal-Mart recently had that sold the movie for only $9.99.
