Preordering ODST - Help Plz

So I live in China, where the Chinese roam.. I'm in foreign lands.. but what do I do when I need to preorder Halo: ODST??!!!

lol, but srsly... I really need to preorder this game so I can get my hands on it as soon as possible.. Does anybody know how I can preorder an American version and bring it over here?

Many problems for this include:
-I guess there's like a location copyright limit for each game, so I need a US version for it to work in my US Xbox 360.
-Has to be English lol
-I've ordered things from Apple and such, so I know I can ship things here pretty easily..

I've heard Amazon is good for this type of thing.. but I'm not entirely sure. I don't wanna spend $60 on nothing, so PLEASE recommend some sort of site or something that can guarantee I will play ODST the first day it comes out...

Please, I will love you foreverz and everz.

...lol

 

Actually, I just looked up Amazon and found out it only ships ODST inside the US.
So.. I just preordered it and sent it to my grandma (who lives in Wisconsin) so she can send it to me.. but I prbly won't get the game for 5-10 days after the 22nd..
