We have been emailed the bill of lading by the shipping agent. The volume is 80% greater (5.87 m^3), the weight is 32% greater (500kg) and there are two packages not one. So we have $600 extra shipping cost than we were expecting based on the size and weight on the proforma invoice.
I'll try and find out the reason for the discrepancy as the extra $600 is rather unwelcome to say the least.
We have the usual spares except for spare LCD and motherboard, and the 100W tubes must weight a little more than 80W, otherwise it seems someone has got their math(s) wrong.
