Happy Halloween! Stop by Harvard Book Store for a special Halloween trick-or-treating shopping experience. From 8:00pm-10:00pm, we’ll be turning the lights off for some spooky browsing among the shadows, where participants will be provided a flashlight (while supplies last). Customers who wear their Halloween costume during this shopping experience will get 15% off their purchase, valid only on October 31, 2026 from the hours on 8:00pm-10:00pm, excludes items already discounted. Candy will be given out, while supplies last. This shopping experience is free to attend, but please RSVP below so we have a rough idea of how many customers to expect.
