I'm not sure what else I can add to the previous reviews, but this place really IS awesome. I can spend a good hour browsing though books here when I have some time to kill.
BMV is a GREAT place to buy gifts. I always find really unique things here for ridiculously low prices. They have lots of new books for super reduced prices. (I just bought my dad a giant hardcover National Geographic book with pullout maps, letters and CDs and only paid $19.99. I just checked and it costs $70 at Chapters and $50 on Amazon. It's still shrink wrapped and obviously brand new. Score!)
BMV has 3 huge floors. It's big and spacious (like an Indigo/Chapters), but unlike most other used bookstores. Their selection of cookbooks and artwork is especially impressive/extensive.
There is not a lot of staff around and sometimes I'm stuck looking all over if I can't find a particular book or section. But otherwise A+
