Referral Link
If a referrer has you as their Ambassador and sends a referral link to a new customer, they'll get a $20 coupon, and you'll become the new customer's Ambassador.
Friend Invite
If the inviter has you as their Ambassador, you'll become the Ambassador for the new user.
*Note: If a customer sends a Referral link or Friend Invite and the new user doesn't sign up correctly with you as their Ambassador, they won't have an Ambassador, even if they clicked the link.
