I went to the Auburn Harvey Norman store today and saw there was some cheap games on sale/clearance for $25, some titles included Crysis, Enemy Territory: Quake Wars, Viva Pinata, Sam & Max: Season 1, John Woo's Stranglehold, and some others.
There was also $15 50Pk Verbatim DVD-R (made in Taiwan) on sale lots left of what i saw.
It seems like its for Auburn store only.
some other bargains may be in the bargain bins/sale items.
