Buy any good box sets lately?

Today, I went to Cheapies (a store that sells used and new blu-rays, dvds, cds) and bought two used box sets on blu ray. I got the Mission Impossible 6 film set, which also has tons of special features and digital copies of the movies, and the Superman 80th anniversary collection, which has 8 animated DC Universe movies and lots of special features. What box sets have you picked up recently?
