Just picked up the double pack of XBox 360 Lego Indy and Kung Fu Panda for $5 total at Kmart Burwood VIC.
They had 2 copies left at the entertainment service desk. I don't know if other KMarts are clearing their stock of this promo pack, but for $5 it might be worth checking if you haven't already got these games.
buy the others and ebay them :)
