I know there are some folks here who plan on getting the new Batman game for the PC. If you are interested in a couple pretty amazing deals, CDKeys.com has the regular version with pre-order dlc plus the premium version which includes the season pass for very cheap. I have used this site a couple times for cheap games. I recently got Skyrim Legendary Edition for $13 and Mortal Kombat X for PC for $15.
Here are the links for Batman:
Normal ($22.99) http://www.cdkeys.com/pc/games/batman-arkham-knight-pc-cd-key-steam
They also have The Witcher 3 for $38.90 http://www.cdkeys.com/pc/games/the-witcher-3-wild-hunt-pc-cd-key if anyone is interested.
