AD2017amI just calculated how much it would cost me based on the dimensions and weight of the last 2 monitors that I shipped. It's $128.00 to $223.35 for the larger package, depending on the speed that I want. For the smaller package, it's $97.50 to $173.85.
So, ballpark $100 (6-10 days) to $200 (1-3 days). This is from West coast USA to the UK.
