Don’t pre order Fallout 4 from Amazon

The release date on Amazon is November 15th, it’s November 10th everywhere else. I’d rather get it five days before Amazon has it.

Can I pre order it on Steam? And is there a way to tell it to automatically download it once it’s available? Says 9 am November 10th for the PC download on GameStop. Internet connection is slow, maybe Amazon will change the release date.
