Have you ever looked at your bookshelf and realized that something big is missing? Perhaps a signed Grey’s Anatomy script? We know the feeling. However, your fate can change with a small donation to a great cause.

Recent Grey’s guest star Sarah Chalke appeared in an episode centered around Kawasaki Disease in Season 9, which she pitched to Shonda Rhimes after her son was diagnosed. Now, she’s working hard to make a test for the heart disease happen. A team of doctors has a prototype, but not enough funding to make it happen. Her solution? Crowd-source the money, and every donation up to $100,000 will be matched by The Gordon and Marilyn Macklin Foundation.

While you probably saw her episode and understand how easily this disease is misdiagnosed, we understand that finding money to donate can be tough. So, naturally, there’s a great incentive. As mentioned above, if you donate or raise at least $27 before June 30 at midnight, you’ll automatically be entered for a chance to win a Grey’s script signed by the cast!
