You do realize that £999 is not "under $1,000", since the pound sterling is worth more than the US dollar? Right now, £999 converts to ~$1,269 USD, well above the $1,000 MSRP.
Or, if you want to look at it another way, the MSRP for that card should be about £788, so finding it for £999 is far from being any sort of "deal"...
All the prices in the UK end up the same as what you get in the US, I.e. if we're told something is $999 by the time you add tax etc. it ends up £999.
So in reality, when you take away the 20% VAT we have, it drops to £832.50, which when converted to USD is $1052.43.
Please don't think I'm justifying the price they're asking for them because I'm not.
Um, no, they don't. If I go to another country (like our trip to Niagara Falls earlier this year), & I pay the price listed in the other country's currency (CAD, in this case),
my credit card is charged the converted price. They don't say, "Oh, they charged you $20 CAD, so we'll charge you $20 USD on your credit card"; they charged me what $20 CAD was worth in USD (hint: it's worth less).
Or look at it from this perspective. Say a friend sent you a $100USD bill as a friend. So then you go down to the bank, hand them the deposit slip for £100...& then hand them the $100USD bill. They're going to look at you funny, & either a) ask you to redo the deposit slip in the correct currency, b) ask you for the additional $27USD needed for a £100 deposit, or b) when you look at your receipt you'll see that you only deposited £78 74p (which, again, is what $100USD is worth as of today). $100 USD isn't worth as much as £100, so they're not going to credit your account for it.
And I don't know why you're bringing up VAT. Sure, we have to worry about sales tax here in the US, & retailers aren't required to include it in the price. But since VAT is included in the price paid over in the UK, & you
have to pay the VAT (unless you have some sort of weird exemption, which I highly doubt) that's already included in the price, I don't see the point of discussing a non-VAT-inclusive price point. That's like saying, "well, nVidia's markup on its cards is higher than AMD's markup, so we should use those figures for price comparisons instead of the actual prices paid by consumers".
