Back in the day a panhandling Bruce McCulloch was a regular feature just outside BMV's doors.
Go here to buy nearly mint back issues of Adbusters for $5 the same month they're on newsstands for double the price. Ironically the basic literature section is not quite in alphabetical order and it's often tough to find the author you're looking for unless you have Selective Book Spine Memorization™ skills like I do. Canadian authors are separate from all the others, so once again, it's hard to find what you're looking for as I can't always remember who (other than Douglas Coupland and Lucy Maud Montgomery) is Canadian or not.
There is a large cookbook and travel section as well as pornography in the back if for some reason you're clamouring to pay money for it. I usually go for the cookbooks and recently released novels but bring a tote bag otherwise you won't be able to carry all of your sweet finds!
