When you’re getting books do you prefer to get new ones or secondhand ones?
I really enjoy the “hunt” for used editions of books that I want, and browsing through stacks in used bookstores is fun and neat way to discover books that I might not ever run across otherwise! But I’m kind of picky about the condition of books I buy, so sometimes I just go the easy route and pick up a new copy. Or if it’s a book I don’t want to wait to read I’ll snag a new one!
Thriftbooks is great. I’ve ordered a lot of things and they have a pretty solid bar for quality, even if you pick the books listed as “acceptable” (which is the worst tier there is).
