Where do you get books? Watch
Are you using them for your studies or really for your interests in reading? most people who said "get them from the library" are talking about university libraries as an addition to their studies in fact. That is my experience I made.
Fiction books I pick up from charity shops unless I'm desperate to read something that's new, in which case I grab it off Amazon rather than wait for months for it to start appearing in charity shops. My closest charity shop does 6 books for £1 including hard backs, it's crazy, but amazing!
I read a lot of comics and graphic novels and there's a great comic book store near me.
I also take books out of the library if they're ones I'm unsure on.
