Tom over at Adoremus Books just emailed a new discount code to me. If you'd like to enjoy 15% off your book order at Adoremus, plus free shipping on orders over $25, the code is AOB208. You just key in the coupon code when you check out. This coupon is good until April 1, 2008.
If you've been intrigued by the books in our little contest here, you'll be happy to know that Adoremus carries most, if not all, of them. They also carry a good selection of homeschooling materials including textbooks, videos, computer programs, etc.
