PC?

[BlairHofstetter]

Trying to buy a game but I'm not sure which one is for a PC?

It just says Mac/Win download or Mac/Win Physical.

I just want to dowload a second expanision pack for my sims 3 but I cant find the pc version.

Mac/Win stands for Macintosh/Windows.  If you have a PC, then you probably use Windows so either version is correct, the only difference is one is a download and the other is the physical copy.
