Black Friday 2018: Get Call of Duty Black Ops 4 for $37

For a game that came out barely a month ago, that's a steal.
Unfortunately, this promotion doesn't seem to include the PC version of the game. Blizzard's Battle.net is running its own discount on the game, but it's not quite as good of a deal, starting at $48 for the base game.
