Quick Godfather question

[Iamspartacus]

I still don't own the Godfather movies and am dying to get part 1 and 2. WIth that said, it seems cheaper to get the Godfather part I and II combo. Here's my question. When you do it this way, do you get both movies seperate or are they in the same bluray case and/or even on the same bluray disc? I really want them separate in my collection. Thanks for your help.
