Economy courier services partner with the local postal service in both the USA and the country of delivery in order to offer a lower cost service. Parcels are taken by USPS here in the USA and they are then sent to an international consolidation center in the USA before being combined with other parcels and sent to your country. When the parcel is delivered to the consolidation center in the USA it is marked as delivered. Once it leaves the consolidation center tracking is very limited and it can be weeks before we know where your parcel is.
