Great prices for games that were only released two weeks ago. XIII-2 is much better than XIII, in case you're wondering. It's $11 cheaper from OzGameShop, but you need to wait for delivery, and it isn't Australian stock (not that that matters). When I bought mine (FFXIII-2) they were giving away the preorder bonuses for free in store, so you might get lucky and get one.
The price was $89 at JB and $78 at Harvey Norman previously.
EDIT: gaaraa has pointed out that EB is selling both these games for $68 each!
EDIT 2: jim999 has pointed out that it's $58 at Big W!
