Barnes & Noble just released a new printable coupon that you can use through December 16th at in-store to save 25% off any one item! I love to give books as gifts, but of course Barnes & Noble has so much more then just book anyways. My local store has a pretty substantial toy section as well.
Make sure to read the fine print on the coupon, and take note of the exclusions. The most notable is probably the Nook of course.
Don't forget to get the Bargain Blessings toolbar to print coupons and stay up to date on all the latest deals!
