goHastings cuts 40% off used books and CDs, 30% off used DVDs, and 20% off used Blu-ray Discs via coupon code "203040". That's tied with our February mention as one of the best discounts we've seen for used items from goHastings. (We saw 40% off used books two days ago, since expired.) Shipping adds a flat 96 cents for book orders, or 96 cents per item for CDs, DVDs and Blu-ray discs.
