Buying a Collector Edition (english) and using in Brazil?

[tityus]

I understand that the easiest way to CoD is to get the digital copy, but nostalgic I am, I'm interested in the Collector's Edition. Therefore, I'll pass on a digital copy.

Also, since the CE apparently uses a different method to validate the game, I`m not sure if it will work from here, Brazil. Therefore the two part question?

(...) Other than a risky deal at ebay, could anyone point me to a place where I can buy a Collector's Edition (English version)?

Also...

If I manage to acquire it, can I legally validate it from Brazil?

Does anyone know?
