Discount codes are available in our newsletter and for special promotions. You can enter them in the first step of the order process to the right of your address details. By the way, upper and lower case is not important when entering the code.
If your voucher code does not work, check whether you have accidentally inserted a space and whether the code is still valid and meets the conditions. Sometimes a voucher code is valid exclusively for a certain product or only for one product category, or it can NOT be combined with reduced items, our sample service or other promotions.
