It really depends. I’m not from US, so ebooks and regular books tend to have very similar prices, no idea why. I can get a regular book for 40 bucks and the ebook will be 30. No great. So I useually pirate all Ebooks I have and if I really like it, buy a paper copy of it. I really like to collect books, so there’s that. Graphic novels, on the other hand, are exclusively physical, I’ll only read a few chapters to see if I like the story, in case I’ve never heard of it, and buy the real one
