Edit: Nevermind, it looks like the Amazon Video versions are only available in the USA and I live in Canada.
Have you tried Google?
It’s $114.99! And that’s the bundle price for all six movies (the individual prices are $22.99 each which adds up to $140)! The Bluray pack for all 6 movies blue 3 bonus discs are $75 at Walmart! And I doubt you get all those extra bonus features from Google Play.
