Thanks for posting. I am going to buy 2 books. One for me and another for a friend. We are buying Washingdon DC books for our trip there this summer. I thought we'd have a better chance of using the coupons in DC than the one for my area, which is 3 hours away. Do you know if they would give $10.00 off each book, or $10.00 off the entire order? I'd just have her order her own if it's not off individual books, but I thought I'd save on the S&H if I could order them together. Thanks again!
