We recommend that you copy and paste the voucher code to avoid typos.
If your voucher still does not work, the following questions can help you find the problem:
Have you deleted any spaces left before or after the voucher code?
Is the voucher still valid?
Does the voucher require a minimum order value?
Are you sure you haven't used the voucher on another order?
Is the voucher meant for a specific brand/campaign?
Is the voucher valid for Zalando or Lounge by Zalando?
