GameStop takes $20 off Portal 2
This seems to be the norm lately at Target as well.

Toys-R-Us has Mortal Kombat for $39.99 and also has an in-store $10 off coupon located at the front of the store, so grab that for another $10 off of it.

K-Mart has Portal 2 at $34.99 and also has a $15 off MotorStorm Apocalypse coupon.

Amazon has matched Toys-R-Us on Mortal Kombat and Portal 2 as seen HERE.

I said it before and Ill say it again, don’t buy day 1 and you can save tons a week later. This seems to be the new flow of these titles. $59 one week and $39 the next. Enjoy the deals!
