I wish to ship a plywood crate 34" x 44" x 6" weighing 21 kg from Surrey, BC Canada (Postal Code V3S 6Y8) to Whitby, Yorkshire, UK, Postal Code YO21 3HD. It contains an amateur oil painting, value CAN$200. Air freight via DHL was quoted at CAN$677 but that is a bit high. So could I get a quote for surface freight? Tony.
