The sound of bells is ringing across the state, marking the official start of the Salvation Army's annual holiday campaign. The Coca-Cola Southwest Beverages Porch visited Quail Springs Mall to learn more about how to get involved.

Stop by the CBS News Chicago studio, at the corner of Dearborn and Washington streets, Friday morning to donate.

From now until the end of the holidays, you'll hear the familiar bell ringing and see the volunteers with their kettles.
