I managed to haggle the price of a new Yamaha 567B Amplifier for $499 normally $899… The best prices I could find elsewhere were as follows
a) JB's Ticket Price $899
b) Online Retailer $799
c) Refurbished model from a place in Hallam $549
So I thought this was a pretty good deal…
The key features I was after were as follows
a) HDMI 1.4
b) HDMI upscalling
c) 7.1 Sound
Looks like you got yourself a great deal. Judging by the receipt you uploaded, purchasing the 55" LED TV at the same time may have helped your negotiation. Might also be an idea to mention Harvey Norman in your title
