Shipping costs will depend to: 1) your address, 2) delivery service available, 3) package size
I use the most common couriers (TNT, UPS, DHL etc.) with on-line tracking service
The package size is very different for each customer. For this reason, the final price of the shipment will be know when the boxes will be ready for the journey and the final dimensions of the box/boxes are known. I can make a rough estimate to know, for every customer, the approximate amount
For the far destinations and heavy loads, it's suitable for the customer to pay directly the courier after the order, with the net price of the shipment. In this way the customer can save some money, avoiding reloading tax and choosing the best price offered by the web shipping dealers.
In every cases I provide instructions about the shipment process
