Once the package arrives in the US, the USPS take over the shipping. Orders can be tracked with the tracking tool found at www.usps.com.

This option is not always available, depending on what you are ordering and where you are shipping to. Registered via NY: Depending on which state you are shipping to, this option will be available in order to try and ensure that there are no delays to your package as it enters the US. Packages are shipped first of all with PostNL to a NY forwarding address and then, from there, shipped on to you. We will update you on the tracking once your order is shipped from the Netherlands and then again once it is forwarded from NY. Updates can take up to 24 hours because we work in different time zones around the world.
