Is there a way to buy a "collection" of movies at a discount via Amazon Video / digital versions?

For example, I bought the Blu Ray version of Harry Potter series (all the movies) for a discounted price a few years back.When I look on Amazon video for the digital versions, it looks like there are no bundles/ I am forced to buy all the movies one at a time at full price. via /r/amazon https://ift.tt/2zIOdBs
