Strand Books announced late last week that their Fulton Street annex will be shutting down for good at the end of August. That means that starting today, everything in the store is discounted 20 percent. It’s got good selection, and it’s conveniently located across the street from the subway entrance, so you might want to make a little side trip. (No word yet if this price cuts will get deeper as the final date approaches, so you’re on your own figuring out the “amazing discounts versus diminishing stock” calculus…)
