I have ended many a date in the Annex at BMV, I just can't stay away.
I love them and I curse them.
I love: their knowledgeable sales staff, their huge selection of classic fiction, that they sell vinyl and DVD's, how cheap new-ish books are compared to Chapters.
I curse: their discount prices that keep me away from smaller independent book sellers, and that the (otherwise lovely) staff can't tell you where anything is. They have typical sections "theatre" "canadian" "food" etc, but organization within those categories is non-existent.
It's open late, and is a great place to get lost and block out the rest of Toronto. It's rare to make it out empty handed, but it's about 80% cheaper than Chapters.
PLEASE NOTE: If a book is still only available in hardcover, they won't have it yet. It's older new books. Think of them as a oxymoron book pusher.
LIFE LESSON: Read more books.
