After learning that the 2006 set was OOP and learning about the changes in the Blu Ray set I went on a mad dash to the Half-Price Books and other used media stores. Managed to pick up all 3 movies for about $40. Still cheaper than going through Amazon, I think.
Has anyone else had success in the 2nd hand market? Maybe there will even be an influx of these discs when people trade in after picking up the BR set?
