There is no limit on how many friends you can invite. However, there is a $500 limit to the total amount of Shopping Rewards an account can earn in referral bonuses.
If a current customer reaches their referral bonus limit, their bonus for a subsequent successful referral may be reduced in order to remain within their bonus limit. However, the referred customer will receive the full referral bonus amount, assuming completion of all program requirements.
Additional terms apply; please see section 9e of our Terms of Service for more details.
