You can cancel your order within the first 15 minutes in your customer account after placing it. We cannot cancel it afterwards, as it moves quickly into processing. If you no longer want your order, we recommend refusing the package upon delivery so it is returned to us. You will receive a refund once our warehouse receives it.
If refusing the package is impossible, within the European Union and UK, please use the return portal https://www.taschen.com/de/returns-portal/. Our return instructions can be found here.
