Dear HONG,
Thank you for choosing Zalora Malaysia!
In regards to your email, please be informed you will have to redeem the voucher at the payment page. Once you key in your credit/debit card details, a "Redeem" button would appear and you can click on it to redeem your voucher.
You may use additional vouchers in the same order as well.
Hope this clarifies.
Have a good day!
