We've negotiated shipping rates with DHL which are in many cases competitive with USPS. DHL's tracking info and customs clearance times are far better than those of USPS. Unfortunately our e-commerce system is not integrated with DHL at this time, so we can't offer DHL as an "official" shipping choice in the web store, but what we will do in the meantime is automatically upgrade any order where the DHL cost is close to the USPS cost. If you want to specifically request DHL, please include a note with your order or send us a separate email.
