My friend, Nicole, passed this along to me and thought you might all be interested as well:

You can receive a FREE dvd through this site. She received Helen Keller but not sure if it changes. You have to respond to the email they send you and then enter the free code they give you in the email on the right of the page for the discount and free shipping to be applied. You do not need to enter any payment info as the balance will be $0
