If you buy US games, you have to buy US download content (if & when it becomes available) As dlc is region locked.
Example I have a US version of GRID. so I had to buy the DLC from the US store. but I purchased the credit from DHgate.com and downloaded it. and installed the DLC content, BUT if I bought the DLC from the AUS for a US game. then the game would not "SEE" the content.
