My understanding is the exclusive Target bonus features come on a separate disc that you get when you buy the 3-disc collector's edition in stores, and the Best Buy bonus features are available online via live streaming with the CinemaNow service, which you can only access by buying the exclusive Best Buy collector's version of Into Darkness. The Best Buy bonus features can also be found on a bonus disc, but it is only available internationally from Best Buy Canada (when I went to their website, they wouldn't even offer an option to ship to the US). I don't know if these bonus discs are blu-ray or standard definition DVDs. The "Enhanced Commentary" version of the movie on itunes can be purchased separately as a 5GB download, or can be accessed via a download code from the Target bonus disc (you still have to download the 5GB file though).

Anyway, it sounds like some of the posters here have already gathered all these bonus features together from different sources, and ripped them to video files on their home computer. (no way am I spending over $100 and going on scavenger hunt for all this stuff, that's why this thread was created!). Who is going to start creating menus and branching for a custom made bonus DVD? The actual blu-ray menu for the movie is fairly easy to come by, you can find it on youtube and I've already ripped it to my computer. I also have the deleted shower scene if anyone wants that file.
