Before I speak about the deal and the thread descends into mis- information here are the facts
you don't need a step down transformer
there are no more custom/postage or any other fees to pay, Amazon charge you for all that so the price you see is the price you pay
The warranty is with Amazon, I have returned things to Amazon US before that are faulty and they always refund the P+P
NOTE! if you are a blur ray film fan, this console will be region 1, so if you own region 2 blue ray films, they wont play
Hope that stops the people who try to claim otherwise.
The price is based on todays currency rate and using a card that does not charge a fee for buying in dollars, DONT use Amazons currency converter either as you will pay more.
You get the Vanguard pre order bonus here as well, as Game can only lock down the UK
if you need a credit card the Post office convert at Bank rate, charge no fee and is £40 quidco (thanks to chanchi for the info)
555 US Dollar equals
326.92 British Pound Sterling
I want to add this here so people see it clearly, you certainly get a 1 year warranty with Amazon, but I believe you will have to contact Sony USA not sony Europe if you don't use Amazon in the year
