I got an email from Book Closeouts, an online discount bookseller that I buy from frequently, that they're having a "back to school" sale with lots of Scholastic and McGraw Hill books discounted a further 25%. Here's the link:

http://www.bookcloseouts.com/default.asp?N=3291&promo=Back%2Dto%2DSchool+Sale&sort=p_TitleSort&dir=ASC&rid=081060

There's over 1000 books listed in the sale. I have better luck narrowing the list by clicking on the categories on the left (Education, Children's non-fiction, etc.).

Also, if you haven't already used it, they sent a coupon code a while back you can use to get $5 off a $35 purchase. In your shopping cart, enter the following code and password:

Coupon code: bookcloseouts
Coupon password: bargainbooks
