Besides being a useful replacement for a missing bed-frame leg, a stack of books also makes you look smarter and can stop a crossbow arrow if you're being targeted by any misinformed vampire slayers. Stockpile these versatile volumes with today’s Groupon: for $10, you get $20 worth of books at Balfour Books.

The multitudinous shelves at Balfour Books maintain a stock of previously loved compendiums, with almost every publication retailing for half the publisher’s original price. Browsing bibliophiles can navigate the stacks and snap up tomes focused on wide-ranging subject matter, including history, literature, cooking, and design, and voracious word worms can navigate the store’s lexiconical labyrinths for word-based pit stops. Fill trouser compartments with compact pocket books ($3.50+), or let young minds build burly page-turning muscles with a colourful assortment of children’s books ($10+). As most titles generally range from $10 to $40-plus, customers can squirrel away an arsenal of volumes to bolster their domestic dens against the harsh sting of book-to-movie disappointment.
