FedEx offers the best courier service around the world. K&S understand this, yet FedEx does comes with a premium. We tried hard to secure the best deal possible, but still no match to the DHL (still a very decent service, we are happy about them most of the time) pricing.
So the solution is to still offer you the FedEx option. So for overseas orders, whenever you want to switch your courier from DHL to FedEx, just simply add the FedEx item (price varies depends on your region) to your order and you are set!
