You sure? The last time I checked VAT is around 20%, not 50-80%!
A good way of working out how much a US or Far East product should cost in the UK is to add 30%.
The 30% will then cover VAT (20%) and the other 10% will cover shipping charges, custom charges, admin charges etc. etc.
When I looked at importing a car from the US, it was the US price divided by the exchange rate the bank was willing to give which is never the exchange rate online, always lower and then add 30% to cover taxes and shipping etc. It does typically work out the same for most items imported.
So is USD price is $600, it would be for instance as a rough guide:
600 / 1.55 = £387
387 + 30% = £503
Then add Etailor margin.
I will be honest guys the price seems far to good to be true, trying to find out from Philips the deal with this monitor but so far no response as no one seems to know.................
