Been slightly cheaper before with cash backs, but $443 is the best around and a HUGE $255 cheaper then JB Hifi!
They also have a bundle for $642 with the extra 55-200 VRII lens. That is what I purchased as it saved me another $50.

And another bundle with a 55-300mm lens as well:

Nice camera. Excellent sensor. Still I'd step up to a D5x00 if you can afford it and a D7x00 if you're serious about photography.
