Buying from the UK from the USA, I always have VAT deducted from the price which is handy because it helps to pay for the extra shipping costs.
I buy a lot of DVDs from Amazon.co.uk and when I eneter my USA address it deducts the VAT from the invoice and shows "0.00" owed.
However, MVC (when they existed) wouldn't do it and charged the VAT, so I stopped using them. No wonder they went bust.
