Benefit is a mobile payment platform that enables users to support their chosen causes with every purchase, without spending any extra money. By downloading the app and shopping at selected retailers, individuals can earn rebates of 2-20% on their purchases, which can be directed towards charities, schools, or other non-profit organizations. The app can be used for immediate in-store or online redemption, making it easy for both individuals and charitable organizations to raise funds quickly and with minimal effort.
