This service is best for small to medium sized items (both furniture and objects) and these shippers transport via both ground and air service so international delivery is available. The shipper professionally packs the items and arranges transport via freight service. These shippers also provide door-to-door service, though you are responsible for unpacking your purchase and often for the disposal of the crate once delivered. Cost varies and is determined by the size of your shipment and your location. Typically, payment for these services is required in advance. This is the only method available for international shipments and a proforma invoice stating the purchase price must be included with the shipment.
