OT: Help With a Zombie Movie

Off topic, but need help with a zombie movie.

When I was younger, I owned a zombie box set. It was cheap. Got it from Suncoast. One of the movies was really damn good and I cannot remember the title. It had a girl looking for her father after he stopped writing her. She travels to a coastal town to find him, and she meets a guy traveling with two woman.

I remember two scenes in particular where one of the girls is murdered by a pack of zombies in a grocery store, while other girl is murdered by zombies in a movie theater.

PLEASE help me with this. It was a favorite of mine as a kid.
