There is a 30% code that I received via e-mail however it's only for some season passes and DLC:

"We’ve selected the following 5 fantastic titles to be smacked with this discount: Batman Arkham Origins Season Pass, BioShock Inifnite Season Pass, Borderlands 2 Season Pass, XCOM: Enemy Within, and finally Assassin’s Creed IV: Black Flag Season Pass."
