a pity, but for those high costs I can afford just 1 BrickPi3 then instead which I ordered now at GR - but not 2 or even 3 all at once like I intended formerly.
(>130 EUR each, i.e. >140 US$, and I have to correct: just about 11 EUR shipping costs - when I once ordered at GR it was a more heavy packet and so twice as expensive )
ps,
amazon.uk is an extremely bad decision as the UK will leave the EU common market - from that date then shipping and taxes and customs will make it for the rest of the Europeans as expensive (or probably even more expensive) as if it had been shipped directly from the U.S.
