Considered as old school by some, kind of myself included, but they are a great place to get books for free. It's really the perfect solution, you get the book that you want (and more than often also find ones you weren't even looking for) and it's 100% free. And on top of that, it will not be left to decorate your room when you are done reading... I guess a couple of books as decoration might be nice but if you read two books per month, in 10 years you'll be looking at 240 books to store. So, how many of you go to the library instead of the book store?
