Officeworks is selling "Microsoft Mobile Memory Mouse 8000" (RRP $149.95) for $82.
ONLY AVAILABLE IN VIC/QLD/WA
During this period, Microsoft offers 25% cash back on the RRP til the end of Jan 2009, which is $40 (takes about 60 days to get that). That means you pay $82, and after cash back, you paid $42.
Even it is ONLINE ONLY Sales, I managed to price matched with HarveyNorman to get one.
It is a great mouse as it can switch between Bluetooth or 2.4Ghz wireless. The receiver can be used as a 1Gb thumb drive as well. (The driver reports as USB hub with thumb drive + wireless mouse attached).
