Purchase one or more selected genuine Microsoft® Hardware products between 1st November 2008 and 31st January 2009 and you can redeem a Cash Back to the value of 25% off the recommended retail price (including GST).
As an example, I saw at my local Officeworks store the Microsoft Lifecam VX-6000 webcam for $69.95 (way under RRP). With a $35 cashback, that makes it $34.95 - bargain if you ask me.
Note I've set the expiry date as 31/01/2009, however, you have until 28/02/2009 to mail in your vouchers to claim the cashback.
cool!
