I suppose that you have now learned to not trust the United States Postal Service with your $10,000 package. FedEx or UPS do cost a little more, but in this case I think you would agree that it would have been worth it.
What DHL doesnt do anymore is US->US (domestic) shipments. International delivery is still definitely handled in the US by DHL themselves.

There is still a direct DHL presense in larger areas/markets like Seattle, San Francisco or Dallas. But not so much in other parts of the country.
