Referral rewards are exclusive to subscription purchases and cannot be used towards one-time purchases. In order for advocates [those sharing their referral links] to get their promotion code, their referrals must complete their first subscription order after visiting through the referral link. If the referral cancels or returns their order, then the advocate will not get a promotion code. Referrals' coupon will expire after 30 days of being issued. Advocates' coupons will expire after 60 days of being issued.
