some time ago there was a deal someone posted for MGS4 $37 - confirmed, but I went to two different Targets to try and get a hold of a copy but it's impossible cause they hardly stock games. Been to JB-HIFI along Chapel St, Prahan and bought myself a copy of MGS4 there was actually a sticker on the box for $59, but a giant sign just above the platinum range saying "all platinum $40". Had to let him know, don't know if that's an issue at all stores.
Also called up Bourke St JB-HIFI to make sure it's at another store.
Just go to EB or something and get them to price match Target's price.
