First, before you ask any questions, look at this guys receipt:

How did he do that? Well, there was a coupon that went out to "RZone" subscribers that gives them $10 off any two games priced $19.99 or less. A lot of "Green-Light" games at ToysRUs are only $5, so with this coupon, you can get an unlimited amount of $5 games for free (as long as they are in multiples of two, of course)!
Before I go any further, I must say this: SAVE SOME GAMES FOR THE REST OF US! I'm gonna head out tomorrow and get do all my Christmas shopping with my only $10 that I have to my name. I am going to get what I can and that's it.
So now what you've been waiting for:
Simply crop the coupon in photoshop, resize it to 2"x3", and go get your Christmas shopping done.
Take care.
