Im not sure if it is weird that I own so many versions of Clannad?

Clannad - Dub Collection & Sub Collection Parts 1~2 & Blu-Ray Collection
Clannad After Story - Dub Collection & Sub Collection Parts 1~2
Clannad: The Motion Picture

Did anyone else buy more then two of the same anime? I don't have the blu-ray in the attached photo.
