Just bought couple things for my new camera. Just put my order at JB hifi today.
Memery cards are quite cheap for free delivery. Sandisk 16GB 45mb/s class 10 for $19.90, I think it's very good price
If you live in Gold coast, use this deal http://www.ozbargain.com.au/node/82017 to get $5 off.
It's not working with free shipping. Sorry mate. I know what you think, I did try.
