Rabbids Go Home - Free Good Guys $50 store voucher
I have given them a call and the $50 "Game Card" is actually just a store credit voucher which can be used for anything. "Game Card" will be valid until 22nd April 2009.
The best thing is, you can go in there and buy one of the older games on the list with a price match (e.g. Gametraders have Rayman Ravin Rabbids TV Party for $29.95) ... but since these are older games, stock might be an issue. Your best bet is to get the newest release "Rabbids Go Home" and price match with Dicksmith for $49 (catalogue scanned here: http://palgn.com.au/media/pics/art_15652_id_11.jpeg).
... in effect you're getting this game for free!
