To compare price, Amazon, Google Play, and Vudu are selling the HD (1080p) version of Live Free or Die Hard for $14.99 (no 4k version offered). FandangoNow has the film in Digital UHD but is also currently priced $14.99.
It’s worth noting Apple is a partner with Movies Anywhere. So, once purchased the movie should show up on other platforms like Amazon, Google Play and Vudu (although video resolution may vary), as long as you have connected the services with one accout.
