Part of Dick's clearance sale at 20% off. Target and Kogan currently have these for $37.00 and EB for $39.95, so a decent little saving.
I checked stock levels for 2000, 3000 & 4000 and all available for click and collect.
Edit: This is the original Sony product and not one of the fakes that are out there.
My local (Knox) has none but their gaming section has been awful for years now.
