MY FAVORITE BOOK STORE! I'm obsessed with books, trust. I have full, massive shelves at home. I can usually find the stuff I'm looking for here, not to mention it's SO cheap. I got the second copy of Hunger Games here for 6.99 (just for comparison).
They also have an amazing vintage magazines and comic books. I'm a big fan, I got a 1964 LIFE magazine from there with Khruschev on the cover (what a cuuuutie!!).
If you're walking around downtown core, go here! It's right next to world's biggest book store and it's 70% cheaper.
