We picked it last week; Sony's PS3 price cut was likely to be undercut by at least one big name retail vendor. Turns out they're all at it.
As mentioned on Lifehacker, Big W technically has the lowest asking price for the 160GB PS3 at $298. Harvey Norman wants a dollar more. JB HiFi hasn't gone down the sub-$300 route, instead offering a bundle with a choice of two games instead.
