I would imagine with Brexit it would be cheaper to order and import from US to the UK now than order from EU.
Firstly good to see the NO PSU option included and relevant price adjustment.
Secondly, I'm curious about this aswell. I would assume the US and EU would be dealt with the same by UK Border/Customs. So to be honest its probably a 50/50 who to buy from. I have however emailed bitshopper.de directly through their website to clarify the issue as currently I would have to pay 19% tax plus I would assume I would then have to pay 20%vat once it arrioved in the UK, essentially paying double tax. If I were to order from the US I would only pay it once.
From what he has told me brexit caused a special deal with EU that makes it easier to ship to UK than even before. I think its some clause that its tax free under 1k Euro.
