Design By Humans does not recommend using a mail forwarding or Skybox service. We do not disallow it, however, we do not support it. If you ship to a mail forwarding service of any kind, the responsibility of that package is no longer on DBH.
These services are often times not reputable and packages shipped to them go "missing" or they claim to never have received them more often than not. Since the package is not being shipped to the recipient, we cannot verify delivery with the intended customer. Due to this, Design By Humans will not support reshipping to third party services if the courier services provides a delivery notification.
Please be careful when deciding to use these services.
