As per title, Harvey Norman currently have the Switch for $448, bringing it down to $398 with the LatitudePay $50 off $150. Looks to be only available in store so YMMV. I could see that both grey and neon were available at Waurn Ponds and Hoppers Crossing from where I am (Geelong).

YMMV. Catch has it at $448, minus $25 Latitude Pay, minus 8% Shop Back today, should take you to a similar price. If you have Catch gift cards from the previous 10-15% off deals, it would bring your net cost to $340-$360 range.
