US games for Xbox?

Does anyone know where I can get import US versions of Xbox games? I don’t want to mod my box because I wouldn’t be able to go on Live! with it.

I have been looking for these, months and months with no success, then I started to order from the US, but the shipping is half the price of the game, I eventually modded my xbox. I was told that you can still play Live with a modded one.

Only has newer games, but it’s free shipping.

Super! That’s just what I need. Thanks.
