This depends on the type of voucher.
Promotional vouchers that we advertise in our online shop (e.g. Home & Living vouchers) can be redeemed multiple times.
Personalized vouchers, on the other hand, can only be redeemed once. These vouchers are not advertised in our online shop.
Please always take note of the redemption conditions of your personalized voucher. If these conditions are no longer met due to a (partial) return, your voucher cannot be applied to your order.
