Yes. You will need to first present the Gift Vouchers and/or Gift Cards, then use the E-Voucher for the remaining amount of the order.
If the E-Voucher has sufficient balance for the payment of the order and it is presented first during payment, then the entire order amount will be paid for by the E-Voucher.
In the event that the E-Voucher balance is insufficient to pay for the order and it is presented first during payment, the entire balance of the E-Voucher will be deducted for payment. The remaining balance amount of the order will have to be paid via other modes.
