There are several possible reasons why you may be having difficulty redeeming your discount code:
It is not possible to use multiple vouchers at the same time.
The conditions, such as a minimum order value or validity period, may not have been met.
There may be a typo or an extra space when entering the code. Please check the spelling carefully. The voucher code can consist of numbers and/or letters.
Make sure that the "Redeem voucher" button has been clicked after entering the code.
The discount code may have already been used on a previous order.
The voucher code may only be valid for products in the sale section or cannot be combined with other discount promotions.
