Barnes & Noble runs multiple different sales, and the end date depends on which promotion you’re asking about, so you have to check the specific offer details to know exactly when “the” sale ends.

Current major promotions

  • A recent in‑store “25% off everything” post‑holiday sale was advertised on deal forums as running from 12/26 through 12/28, ending on December 28 at close of business.
  • A long‑running “Buy 1, Get 1 50% Off Books for All Ages” promotion is listed as valid at BN.com and in stores from January 1, 2025, through December 31, 2025, ending at 11:59 pm Eastern online and at close of business in stores.

How to tell when your sale ends

  • Look at the fine print on the email, coupon, or web banner; Barnes & Noble usually includes exact start and end dates and any “while supplies last” language.
  • If you saw the sale mentioned on social media or a forum, double‑check against the official Barnes & Noble offer terms page or your local store’s signage, since local stores can have slightly different promos or dates.

If you’re shopping right now

  • If your sale is the “25% off everything in store” post‑Christmas offer, plan as if it ends December 28 at store close, unless your store signage says otherwise.
  • For the year‑long BOGO 50% books promo, you can assume it runs all the way through December 31, 2025, but remember it may exclude some items and cannot be stacked with the Premium Membership discount.
