Every now and then big mainstream retailers in Australia run these sales. Actually good sales. I know, crazy right. Big W tends to do it quite often, but today it is the turn of Target to bring sweet deals to the Australian public.
This little link in particular has some brilliant deals for some surprisingly great games at $29 and under. Assassin's Creed III is $29 on pretty much all formats, as are almost all of the Call of Duty games. Dishonored -- which was amazing and more people should play -- is only $29.
Max Payne 3 is another one I'd recommend: $23 is pretty decent for that.
Oh, just noticed Skyrim for $29 and Red Dead Redemption for $23. Man, this is good.
