Late in the game yesterday we added a Gamestop coupon that basically grants you 15% off anything (consoles and tablets excluded). It's a killer deal that we don't want you to sleep on, so we're going to outline some suggestions for what to put it toward, and gently nudge you to use it before Gamestop realizes it's too good a deal. Use code PAYPAL15 for the 15% off and SAVER for free shipping. [Gamestop]
Playstation Plus 1-year membership | $43 with coupon
Infamous: Second Son Collector's Edition | $68 with coupon
Infamous: Second Son | $51 with coupon
Watch Dogs | $51 with coupon
Ground Zeroes | $25 with coupon
Update: The codes are definitely working on some things and not others, hopefully it works on the thing you want.
Don't use it on the One or 360 versions of Watch Dogs, because those already come with a $10 LIVE credit when you pre-order.
