Have any readers that you need to buy for on your shopping list? Here's a really great coupon for 40% off any book from Barnes & Noble for you to use, and you do NOT need to be a paying member of their membership program to take advantage of it. I haven't come across many of these non-member coupons, so I'm definitely going to use it. The only catch is that you have to pay with a MasterCard. Not too difficult to do. And you can use it once in store and once online. It expires Nov. 30, so get shopping!
