For everyone wondering where the stills from The Beast from 20,000 Fathoms, King Kong and Them! were in the movie, the riddle has been solved!
The stills were inserted randomly throughout the movie in a subliminal manner (so they pop up for about split a second frame or two, then go away). Think Captain Howdy in the Exorcist.
For a screen shot, check out Dread Central's review of the DVD.

Also, Slash Film has an article on the different exclusives offered from different stores (four different chains offering different exclusives)

Personally, I think the only ones worth any interest are the FYE tin package and the Best Buy Production Diary disc.
