Please note that our discount codes are tied to certain conditions. You can always find these in our email to you or on the website from which you got the code. Some discounts do not apply to subscriptions, as these are already reduced by 17% compared to the normal price. As soon as you have a subscription product in your cart, this is already considered a discount. Other discounts not applicable to subscription products cannot then be used for the entire cart. If your cart meets the discount conditions but the code still does not work, please contact us through our contact form (section "Order Difficulties").
