AhhhhSooo... My bad for misreading!! In that case I'd do the 2nd hand bin at JB HiFi and EB Games - We are a bit lucky over here as most shops are selling "new" stock that was delivered months ago! The only hassle is that most games are pulled from the cases over here so you might not get the one you see on the shelf...
When I get home I'll take a photo or list my YWW disc details (5.3.2) bought release day.
Listing the details might be more helpful, the label on the underside of the disc is REALLY tiny and hard to see without a bright light.
