We are happy to offer optimized shipping from UPS, DHL, and USPS. Shipping providers used for individual orders are analyzed at the time of shipment based on the weight of packages and delivery location. We utilize different providers for several reasons, most notably to improve reliability for our customers, avoiding lost packages and frustration for all, and cost savings that we pass on to our customers.
For some deliveries, the package may be transferred to the post office (USPS) for final delivery instead of being delivered via the original shipping provider.
