DHL=German Post, DHL delivers everything, even if its not sent from the origin country via DHL (besides UPS,FedEx,TNT,GLS,DPD and other couriers).
Means if someone send something via Thai Post (Reg. Airmail) for 5$, DHL will derliver it to my door.
And you WOULD be surprised about the DHL tracking system, because it SUCKS. I sent something via Express Airmail to Rotterdamm via DHL, paid 45$ and I have to CALL (!!) to get tracking status. Cant do it online. Dont ask my why. On the other hand, packages from far east, track just fine!
