tbh, if you don't got a desktop don't even think about dvds, comics, posters, figures, manga, etc. even a barbones pc is a pretty big quality of life upgrade from phone only. If you got a laptop already, then that's a bit different story. decent sized drives for most laptops are not hugely expensive, and will let you start building your archive. for swag merch, it's nice to be surrounded by the images of things you like. I used to be into wall scrolls for that. posters, similarly. a figure or two of some stand out waifu/husbandos. but dvd/bluerays are so much less useful than a 256gb flash drive filled with mkvs when the internet is out. quality can be just as good, but no dealing with picking a disk, putting it in your player, and oh no, it turns out it's the xbox one and you never watched dvds on it so it needs to download the player from the online store and now you are screwed.
