Went to Kmart at Chatswood NSW today and saw they had the Wonderbook Book of Spells for PS3 listed at only $5, which was a bargain in itself since this is the game and the wonderbook. Even better when it scanned for only $2! Great if you have kids and don't have it already.
There was another 2 left after I picked up mine, but it should be the same price in all Kmart stores that have stock.
Also there was lots of Diggs Nightcrawler Wonderbook edition available for $15 on clearance or the game itself for $9.
This is a total bargain for a really quite underrated experience, should magic/Harry Potter be your kids' (or your :)) bag…

Note that you need to have PS Move and the camera though for it to work.
