To use the coupon, you need to have a Tiger Prime Account with available funds greater than or equal to the exchange amount or equivalent to ensure a successful debit.

After the client clicks "Pay Now" and the deduction is successful, the exchange voucher status will be updated to "Share(s) being delivered", share(s) will be issued to client's holding position within 10 working days.
