You can find it on Amazon UK, but not Amazon.com. And, to save you the effort, the one listed on Amazon UK won't ship outside of the UK. (At least, it wouldn't ship to the US or South Korea).
They do also have them on
ebay, of which the price is almost the same, depending on the exchange rate - the shipping is much cheaper, but the cost of the cover is more expensive. I ordered mine from ebay a couple of days ago and they shipped it eight hours after I bought it, so that was impressive.
