Yes, if you have a discount code, you are welcome to redeem it when you set up your subscription.
Please note that the respective discount only applies to the first subscription delivery. For all further subscription orders you pay the normal price for the coffee in your subscription.
Please enter the code in the coupon field in the shopping cart before you click on "Checkout".
By the way: you can also redeem a gift voucher with your first subscription order. We are working on a technical solution so that the remaining value of your gift voucher can also be used automatically for further subscription deliveries. Unfortunately this is not yet possible.
