ordering from Amazon.com instead of amazon.co.uk

[Carameli]

has anyone done this before as Lego seems a lot cheaper.
I just put a star wars fighter into my basket and with delivery came to £16.84 which is a lot cheaper than the £20-£25 I have seen it over here.
But wondered if I would get stung with customs fees etc?

Does anyone know?

i ordered a book and had no extra to pay, it arrived ahead of schedule. the book would have cost about £48 in England but i got it from America for about £35
