Hello @Seller_pwYKuPSgrmxIg

In regard to your question, for vouchers, in general, these are set for a specific product, not for specific buyers/customers. Here are some help pages related to voucher info that may help you:

For any more specific, my advice will be for you to reach out to our support channel, to confirm if there is any other promotional option available.

Any assistance, don’t hesitate to reach out to our support channel.
