Christopher is correct on this.
Forget VAT for a moment, the price I use to pay at CVP / 'RED UK Europe' will now have an added customs charge/duty as if I bought it straight from the US. I have already experienced this with Swedish customs and the postal service. Read the new EU/Brexit rules and see.
Oh... and I should add it is not just about purchasing and saving money, but more importantly, about having a dedicated RED office that can really provide service and support here in Europe.
