I'm planning on stopping (or at least massively cutting back) on buying anime BDs/DVDs and eventually moving to streaming when I finally finish all the series I've amassed over the years.
I've never rewatched an anime series (except Haruhi), so there's really not much point in buying physical for me. I finish the show, then they just take up space on a shelf or in a box or whatever.
I've started selling some of the shows I've watched and already made a little bit of profit against what I originally paid for them, which is nice!
Since I've subscribed to streaming services, I've realised how everything is in one place and on the go (mobile, Switch etc.) in such a convenient way. Everyday I'm eyeing my physical media shelf telling to it "I'll sell you" like a crazy person.
I've been going on a massive physical clear out and feeling much satisfied with how much space is created as well as making way over the original price paid.
When it comes to Physical Vs Digital, my thoughts are simply this. Purchase physical media you are genuinely happy to get and/or wish to avoid the risk of selling out.
For every other title you're curious about but uncertain to buy or not. That's where streaming comes in where you have access to a massive library. No more commitments or paying for each title you could possibly feel money is wasted.
Though for titles that aren't available in the UK or on any streaming platforms, then go for a physical (while avoiding paying donkey prices if possible 🐴)
