Of course, you only have to pay for the articles you keep. An invoice will be created as soon as we receive your returned articles and enter them into the system. Should we not receive anything back from you, we'll assume we did a great job and you want to keep everything. In which case, we'll send you an invoice for the entire MODOMOTO-Box. The invoice will be sent via Email. You can also review your invoice online, and download it at any time from the user dashboard by choosing 'My Boxes' from the menu.
