Amazon: Portal 2 for Xbox 360 or PS3 Preorder + $20 Credit only $55

I don't normally post Video Game deals but this is quite a good one so I figure it may help someone out there! 

Portal 2 comes out in April and right now on Amazon when you pre-order it for $54.99 you will get release-day delivery (with Amazon Prime or Amazon Moms) PLUS you will get a $20 Amazon promotional credit for free! 

If you have a hubby or son who is going to want this anyway -- I definitely recommend taking advantage of this offer!

You can get the 360 version here and PS3 here.
