Same here, since I'm not signing up for Disney+ just to view the Guardians of the Galaxy Holiday Special. I would much rather own it. Even without viewing the Holiday Special, I was still able to follow Guardians of the Galaxy, Vol. 3, so I don't get that some people have suggested that you need to watch the Holiday Special first (I also haven't seen Infinity War or Endgame and didn't feel confused at all, though perhaps that's why they had Peter sum it up in the elevator scene, for people like me that have yet to see those films). Perhaps I'll buy them along with the Blu-ray for Vol. 3, since I don't do digital movies. I hardly have any games on digital, let alone movies or even soundtracks, since I buy the physical versions of those).
