Halle Berry, Robert Downey Jr. and Jon Hamm are among the stars involved in a great auction at Charity Buzz, and there's still a chance to get in on some cool opportunities.
PICS: Must-See Celeb Sightings
If you go bid on CharityBuzz.com by Tuesday, you could join Zac Efron on the set of his next movie, have lunch with Chef Carla Hall and attend a taping of The Chew or go backstage at the Broadway production of Cabaret with Alan Cumming.
The proceeds of the auction benefit Communities in Schools and DonorsChoose.org. Check out the video below for a look at another notable charity -- Rebels With A Cause.
