You can earn extra points by inviting your friends to use Carrot Rewards. Just go to the “Friends” tab in your Carrot app. Click the "Invite a Friend to Carrot" button to invite friends by text, email or social media and share your user code. When your friend signs up with Carrot and enters your personal user code during the signup process, you will earn extra points (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 10 days of signing up to Carrot. They must also fully complete the registration process and confirm their email.
Before you ask, there is no limit to the number of friends you can invite. The more people you invite, the more rewards you have a chance to earn!
