Enter certificate or coupon number
If you have a gift certificate or coupon to use up, please enter the code here. Please make sure that you enter the complete and correct code, including letters, numbers and/or dashes.
Please also take note of possible error messages which may occur during the processing. A gift certificate or coupon number can only be used once, and only within the given time of validity.
If the system does not accept your gift certificate or coupon, please check if it has expired or been used on a previous occasion. If you are sure that neither is the case, please contact us by using the link "report a problem" at the bottom of this page.
Gift certificates can be purchased in our shop at any time. Coupons are granted occasionally by Astrodienst for marketing purposes.
