And looking at their Ebay site seems you can also win a lunch with Colbert, a meet n greet with Katie Couric, A meet n greet with Starbucks founder Howard Schultz, a days of our lives set visit, A Jay Leno meet n greet (which you can do for free in the first place....but hey...the money's going to a good cause), and an appointment with Dr. Oz.
