The biggest reason why I stick with physical is because it’s actually just cheaper still. Digital copies of films are so overpriced as they generally cost more than physical and don’t have any of the extra features most the time.
Also I just love the look of all my disc cases on my shelves, and when I buy some while out it’s nice to stare at them on the way back home. And taking the wrapping off is a lovely experience.
While I don’t buy music physically, I do buy it digitally from sites with no DRM, so that I fully own it and can play across my PC + phone. Again, this is cheaper as I can buy a whole album for £10 which will last me several months on its own, while a single month of Spotify is £12/£11 for Apple Music. And it means I support the artists more!
