Classics customers know why used books are the best. They are half price and cheaper (no $34 hard-backed mystery novels), they are good for the environment (how many stores sell almost all recycled goods?) and they are good for the community (coming, as used books are, wrapped in used bookstores–which are more likely to encourage local authors, literacy programs, poetry jams, games nights, book clubs, knitting groups and hanging out with your neighbors).
In addtion, used bookstores are that sexy, dishevelled neighbor who actually wants to talk to you over a cup of coffee, rather than that uptight car salesman who wants your $30 and get out of his face.
Huffington Post has a list of 13 reasons you should always buy used books. You can read it here.
