XCOM: Enemy Unknown is as much about financial stability as it is about shooting down aliens. That's why if you're serious about defending the earth from extra terrestrial invasion you'll want to take advantage of Gamestop's offer this week. Saving $10 off the cover price you'll have a few coins left over to grab the Slingshot or Elite Soldier DLC to help fend off the invaders.
