You can earn extra rewards by inviting your friends to use Carrot Rewards. Just go to the “Friends” tab in your Carrot app, and you will be able to find your user code. Hit the “Share” button to invite people by text message, email or to share on social media. When your friend signs up to Carrot and enters your user code during the signup process, you will earn extra rewards (and they will too!).
Please note that a user can only be referred by one person, and that in order for you to earn rewards for referring them, they must enter your personal bonus code within the first 10 days of signing up to Carrot.
