I am trying to track my shipment without success
Most of our shipments are sent via the US Postal Service and its affiliates around the world. Unless you choose Express Service, these shipments do not offer real-time tracking particularly for International Shipments. The information provided will allow the Postal Service to investigate internally a misdirected or lost shipment, but will not allow for real-time tracking of a package. Do note that due to the level of service and the volume handled by these services, it is common to see "Information not available at this time." This is not an indication of anything wrong but rather that your package information was not updated on the provided web site.
Real time tracking is available only for shipments via UPS or FEDEX (including Ground in the US).
