Was at Mankato, MN Sam's Club today and they had God of War 3 for $6.91. Not sure how YMMV this is, but definitely a steal even with its recent price drop to $29.99.
You are probably never going to find deals like this outside of one store.
Once an item is discontinued individual stores are allowed to mark the ittems down , usually at the rate of 10% a week till they sell.
Works the same at BJs, Costco, Sams.
So great if you live close, otherwise you're boned.
Usually when you see a price cut like this at Sam's it is on an open-box/shelf copy. Still a good deal, but once someone buys the single copy that's it.
