Element14 is currently out of stock in Australia on the NOIR camera, so shipping time is about the same, so I'm going to mark this offer as expired since it's not the best deal available!
Although it's not advertised as part of their 12 December Deals promo, I suspect that this is part of it:
Element14 currently has the official Raspberry Pi NOIR Infrared camera listed for $18.80 exc GST which works out to $20.68 including GST. Shipping is extra unless your order total is at least $45.
Cheapest that I could find on Ebay for a NOIR Raspberry Pi camera was about $26 including shipping from Hong Kong.
There are a number of other specials running but be careful if you try to use another deal at the same time - at least some of them will cause the price to jump up significantly!

A use for buying multiple cameras - set up hidden security cameras around the house.
True story: Our home was broken into recently - the perps were quickly caught due to a security camera that I had set up. I've been working on more advanced cameras using the Raspberry Pi that detects when we're not home and sends us a text message when movement is detected as a silent alarm.
This is a good deal, but the thing that disappoints me with Element 14 is that you don't take paypal.
Out of interest I have a Raspberry Pi connected to a 3G modem running on solar power as a security camera on a remote property using MotionpieOS. It works really well.
