Donate4Free: Sunkist S'alternative PledgeI’m sorry you missed this freebie, but please check more Free Samples currently available. Pledge to live a S’alternative lifestyle for one week and Sunkist will donate $1 (up to $10,000) for every pledge made to the Sister to Sister Foundation, the first national organization dedicated to women’s heart disease prevention. You are pledging to replace the salt shaker with a fresh squeeze of a Sunkist lemon to reduce sodium intake in an effort to reduce risk of high blood pressure, heart attack and stroke while maintaining flavor. This promotion ends May 31.
