Also, as a new customer, you can get a $10 discount if you refer yourself :) Just follow the instructions here: http://www.fishpond.com.au/helpdesk.php?question_id=1073. For some reason though, it didn't work for me. The coupon code you will receive seems to be listed here (http://www.ozbargain.com.au/node/10909), but seems that it doesn't work.
Anyway, $450 - $30 (moneyback from https://secure.moneybackco.com/merchants/Fishpond/) seems a pretty good deal. If you still going to buy it at the release date and you don't want to buy it from Fishpond, see if any store will match this price of $449.97.
Anyone know of any fatty PS3s going cheap now that the slim one is coming out?
