expired Civilization V: Gods & Kings DLC - $21.89 Pre-Order
This was posted 11 months 4 days ago, and might be an out-dated deal
My first bargain post! In case you missed the previous sale from GreenMan Gaming, this one is even cheaper!
Not 100% certain of expiry, but I would imagine its for one or two days only.
Steam is selling it for $44.99, so this is a great deal. GetGamesGo is a reputable store (bought from them several times, no issues whatsoever).
NOTE: The base game Sid Meier's Civilization V is required on Steam in order to play this DLC.
