Do you buy physical books you have already read?
For example; I have read a book named “The Words We Keep” digitally. I loved it, it really resonated with me because it’s about something - I personally have and struggle with as well.
Thinking to buy the book physically but feel like, I can’t justify it due to the fact that I’ve already read it.
I don’t really re-read books either.
My rule is basically: If it’s visually interesting, such as a good graphic novel or something with good art, I might go and buy the physical book after I’ve read it digitally. Otherwise, if I intend to lend it out, I’ll get the physical copy. Most of my friends aren’t e-book people, so it makes sense.
