Most places will price match - so if you're happy to do a little research & catalogue collecting you will be able to find the best price!

We got ours from Myer, but at the time they had a 15% off sale on games & consoles.. but JB HiFi and Di@k Smith are usually the most reasonably priced.

On average I've seen the console for $388 and the Fit for $134 I think... HTH
