I don't think you get these here with Samsung UHD TV's, so would be worth buying if you use YouShop to buy stuff overseas.
Comes preloaded with 10 UHD movies and 30 documentaries.
Movies: G.I. Joe: Retaliation, World War Z, X-Men Origins: Wolverine, Night at the Museum, The Counselor, Forrest Gump, Star Trek: The Future Begins, Star Trek: Into Darkness, Life of Pi & The Book Thief
Good for $50US, advertised usually at $400US
