Unasked for advice from an old, old Auntie
Now that media is being sold on blu-ray, dvd and CD formats again, some of you might not have the proper players. Many already do, or know how to get them, this is not for those people. I'm not trying to talk down to anyone.
In my humble, and non-expert opinion, the best thing to do is get a blu-ray player or external player, because it will play blu-rays, dvds and cds.
Best External Blu-ray Drives
Or look to a ratings website or organization which you trust.
But if your budget is like mine, you need something more afforable. You can look on ebay, Amazon marketplace, or any other stores that show you the links for used items, to find a drive or player at a lower price. But buyer beware! Check out the seller's rating, and how many people have rated them. Read the most recent ratings to see how your purchase might be handled.
You might want to see an actor's (musician's, writer's, director's) earlier work. That might only be available on dvd, or blu-ray, (or cd). Same rules with the used ones there.

Check the condition descriptions on the site you're buying from to be precise about what you are getting.
Of course, most media can be rented or bought from streaming services. No one in 2024 needs any advice on how to do that. This is only for those of you who want to own what you buy, and sell it later if you find you don't want it anymore.
Good luck! Happy watching!
