To purchase digital games from Amazon US, use your UK Amazon account, and add a US billing address to your account. This address needs to be a valid US address, but nothing will be sent there, and you can access all your games through their website. Some card issuers may charge a fee.
Note: This is the US version. I have no reason to believe it will be region locked, but can’t know for sure that it won’t be.

Coupon doesn’t work. Tip for buying from the US store does.
It did work at time of posting, looks like they have stopped the coupon from working on (some) preorders now.
