For each paid service purchased by your invited customers where the offer card/confirmation expressly states that the Program applies and that Bonus accrual is provided, you will be credited with Bonuses.
Bonuses may be used as a discount only for those services where the interface expressly indicates that Bonus redemption is available and specifies the maximum redemption amount.
Bonuses remain valid until they are used, unless otherwise stated in the terms of a specific promotion and/or in the Personal Account.
