American Idol's David Cook applauds during a concert at the Power & Light District on May 9, 2008.

KANSAS CITY, MO.  --  T-Shirts celebrating American Idol contestant, David Cook , are in demand.

The American Cancer Society began selling them Friday during Cook's homecoming tour. They are $10 and 20 percent of the cost goes to the American Cancer Society in honor of David's brother, Adam. Adam Cook suffers from brain cancer.

The shirts sold out quickly on Friday, so the American Cancer Society began working hard to get another printing ready for this week.

How to get one:

There are a limited supply of shirts. So, for right now, American Cancer Society volunteers will be selling them in the Town Pavilion Rotunda (1111 Main St., Kansas City, MO) on Tuesday, May 13 from 10 a.m. to 4 p.m. or until supplies last. They request you pay cash only.
