Ben Affleck and Matt Damon are offering their fans a chance to hang out with them.

The dynamic acting duo are trying to raise money for their favorite charities: Eastern Congo Initiative and Water.org.

To enter, fans need to go to omaze.com/experience/hang-with-ben-and-matt and donate to the charities. There are varying levels of donations and prizes, with one lucky fan winning the ultimate meet-and-greet.

The winner, plus a friend, will be flown to Hollywood to meet Ben and Matt and be their VIP guests to an event. Flight and hotel is included.
