Target has it for around $30, which is standard for 4K Blu-rays.
Keep in mind, this is a Fox title so it’s technically a Disney title, and, as we know, Disney and Amazon don’t mix.
I've ordered this. I enjoyed Branaugh's other film in the series (and hear there is a third one coming), and I recently revisited the original Express and Nile films in their recent blu-ray releases.
