Those other replies mentioned something about a deal. I don't ask for that.
When you buy the base game on Steam, you must also buy any DLC on Steam. Otherwise you must buy them again, in that other store. Console and PC don't cross.
Can you tell me the differences and benefits between these stores? Just only PC, will be nice.
Most stores list what keys they sell, typically under details for the DLC or "Platform" - if it says "Steam key" then it will give you a code that you then add to your Steam account to unlock the DLC on Steam.
