Basically I was at officeworks today, and I noticed that they had the above laptop advertised as a Acer 4714G-434G50Mn (notice the 50mn, means 500 gb HD instead of 640) Anyway, at domayne they are advertising the Acer 4714G-434G50Mn for 798$ (after 99$ cashback), so I went to my store (southport) and they were able to match it, as the ticket says the laptop is the 50mn, but the laptop you get is a 64mn. I think that they fixed it at southport (after I bought it).
But anyway, I called up another store (west burleigh) and they had the same error, and after them confirming with domayne that the price is 798, they were able to price match it once again, and my friend got his from there. So the bottom line is, I am pretty sure they made this mistake at all officeworks around Australia, so you can try your luck.
End Result? 758.10$ for I5 430 m, 1 gb (320m) dedicated graphics card, 640 gb harddrive, Wireless N, 4 gb ram, HDMI out AND a 14 inch laptop (res is still crappy but whatever). Pretty awesome deal :D Even better im traveling at the end of the month which makes it roughly 680 after gst back :D

:D Enjoy =]
BTW not sure how long Domayne is having their special for, but as long as they are, they will price match..
Edit: Please see the image below for clarification on what I mean about them wrongly naming the product. Notice the 64mn on the price thing, but not on the description ;)
