this is a joke, right? at least it's funny, I don't want to be mean but that's just soo low (it's Sanctum 2 not 1)
I can get you the Dark Souls key for Sanctum 2, can trade first too since I don't have rep.
As long as you have a valid credit card from anywhere, you can buy it yourself, just get any valid US billing address and enter it.
This comes up semi often on reddit.
Now me personally, I didn't fake my address ever if you want a personal opinion, because I am from USA, but I have used a fake credit card number for them in the past (they require a credit card even if you have gift card money) so it's the same kind of thing. As long as you have the funds and it checks out, they don't care.
Make sure you don't have any specific country fees to account for though. It's at least worth looking into since Sanctum 2 is a fairly new game.
I'm really looking for a key for Dark Souls Prepare to die edition, unfortunately I don't live in the US and so can't buy the game on Amazon where it's on sale for 7.50 at the moment: http://www.amazon.com/Dark-Souls-Prepare-Edition-Online/dp/B00917DBUE/ref=sr_1_2?ie=UTF8&qid=1368724557&sr=8-2&keywords=dark+souls
I can offer you a key for Sanctum 2 for it
