I feel very sorry for you guys.. that's insane to be charged so much for an item that you are NOT selling but just sending to get serviced... Already the shipping fee is enormous...
I suppose for European customers it will cost less, first because it's less far but also since the EU rules for goods circulation are still applying for the UK in 2020 despite Brexit.
I don't know why Smyth Research did not use their business account in the first to organize the shipping and charge you for the bill, it would have been much cheaper.
Maybe they were afraid it would take a lot of time and paperwork to do it for all the unit that will be upgraded, and since they are already late on schedule, they chose to leave this to customers asking for the upgrade...
