Amazon currently has a deal where you can get the blu-ray edition of Star Trek: The Compendium for only $11.99. The Compendium includes both the original JJ Abrams’ version, plus Into the Darkness.
Director J.J. Abrams’ global sensations Star Trek and Star Trek Into Darkness set a course for the ultimate comprehensive home entertainment package in Star Trek: The Compendium. Packed with previously released Bonus Material and additional Never-Before-Seen Footage, this collection is the definitive resource for the Star Trek aficionado.
According to the comments, another bonus of this version is it uses the proper aspect rations for large TVs rather than using black bars at the top and bottom of the screen.
The only real complaints are on the packaging. Apparently, the trays that hold the discs are really flimsy.
Either way, I’m personally in for one. I haven’t bought either of these yet!
