I went to a bookstore recently and went home with over 12 used books and not one of the books were over $5.20.
I wish I could be so lucky. Books in Australia (where I live at least) are $22 most days. It's an utter rip off, considering I can get the same book if I lived in the UK for more than 50% off that price. With free shipping. Sometimes days before release date.
Australia is hopeless when it comes to books.
