This isn't THAT great of a deal, but maybe I'm just posting it because I'm nostalgic for the glory days of Borders coupons. Now through Dec. 8, you can get 20% off one item at Barnes & Noble's online store using promo code T3N9N3L.
Of course, that doesn't really make up for having to pay shipping unless you hit the $25 free shipping mark, so it's probably best used on a bigger-ticket item. Sadly, the Nook e-reader is excluded from this deal, but it looks like just about everything else is fair game.
Oh, and all cookbooks are 50% off at B&N.com today, too!
