Dick smith will be having a gaming sale mid next week (Different people have been told 10th or 11th of April, I was advised the 11th by our local dick smith store in Oamaru). There was quite a few games in the pile they were marking down (couldn't see any of the games unfortunately but they were for different consoles) behind the desk I was advised all prices of marked down games would be between $1 and $10. So might be something to go in and ask about or head into to your local dick smith next week to check out.
Australia are having a similar sale as well coming up next week
