We use USPS, UPS and DHL for all international shipments (including Canada).
USPS and UPS Mail Innovations are the lowest cost options, but the tracking can be limited. DHL eCommerce works by using the global DHL network for the majority of the journey, then handing the packing off to your local mail carrier for the 'last mile'. For this reason, you'll see the UPS tracking, and the local carrier's (Postal Service) tracking link on the UPS tracking page:
You can sometimes use the Postal Service tracking link for more accurate tracking once the package is in your country.
If you upgrade to an expedited option, your order will ship via DHL Worldwide Express, or UPS Expedited (we'll pick the best option based on shipping time, previous shipment experience and cost).
Both options are much faster, taking around 3-5 days to deliver to almost any address. Although the cost is higher, we strongly encourage you upgrade the shipping service if your order is needed by a specific date. As with all of our shipping options, we make no profit, all costs are provided real-time from the carriers.
