The best deal I can think of is getting a used copy from GameStop.com. It's $55, so use CAG16 to get 16% off and SAVER for free shipping. It will probably end up around $48 after taxes. That's unfortunately one of the better deals you'll see on this game. The Show just seems to retain its value for quite some time.
Buying used from their site is often a toss-up, but The Show is a newer game, so it's less likely you'll get a crappy copy. And if you do, you can return it to any GS store.
