I absolutely love this site, I use it for all my computer needs and camera needs...but I must admit it isn't the best for camera stuff, more computer orientated.
But anyway it searches for the best current price from the shops in its list from shops across Australia...it also shows which state the shops are located. So if you are afraid of internet shopping you can find the cheapest price in whichever state you live in and see if you can visit a 'brick and mortar' shop.
It helped me find my 450D kit with 18-55 from Road Mogul (internet shop, but based in Abbotsford near where I live) for the price of $954...then it was $19 for courier. Recieved the Camera in two days...(but got the courier tracking info a week later...bizarre)
