What's more, not all are second-hand books. Plus, there can be really great finds of books in pristine condition at such a low price. A great example is my copy of Quidditch Through the Ages which I bought at Booksale for only P40. And it's really a new, non-doodled copy too.
So, if arranging to meet with someone at the mall, instead of spending already by sitting in that cafe, why not arrange to meet instead at one of these bookstores? You just might find childhood favorites there.
