Clarissa Peterson of First Book wrote this to me, and I promised to share:

August 26 and 27 are Borders National Benefits Days. First Book is handing out a coupon for 10% off at Borders on those days – and an additional 10% of purchases made with the coupon will be donated back to First Book by Borders. A good way to save money on back-to-school purchases and help First Book at the same time.
