Locate a DHL service location. You can search for it online at DHL's website. Once on the website, click "Express" at the top left corner of the page and choose "Shipping" from the drop-down menu. On the following screen, enter your country and zip code in the "Find a Service Point Location" box and click "Go."
Drive to the location and choose a box that fits your needs. You will pay a set fee regardless of the weight of the packed box.
Take your package to the clerk and let him know where you wish to send the package. The clerk determines the final pricing based on the destination and the size of the box you chose.
