Just recently I walked into Barnes & Nobles to get a children's book as a gift for someone and came across a fundraiser that was going on. How it works is you can pick any book in the children's department and pay for it upfront with your other purchases. You tell the cashier what book you want donated. The cashier at Barnes & Nobles said it goes to the Collin County Children's Advocacy Center.
I took some pictures to show you how the fundraiser was set up. Sorry for the glare in the pictures.
