only go here when ocad isn't in session. i stopped in a few times during the summer and thought prices were generally OK, but then had a huge shock when classes started up and there was a 1hr line that wrapped around the store. it dies down after the first few weeks, but there is *always* a line while there are classes in session.
if you have the time for a little walk, gwartzman's is cheaper and friendlier, but aboveground is more widely stocked if you don't mind the wait
obviously, they have a student discount so don't forget to show your card
