Went to Woolworths to buy the two boxes of Ferrero Rocher for $10 and saw this deal as well. A saving of $16.79 or thereabouts (my phone camera sucks) - can't complain.
The box can't be seen well in the linked picture, but here's an image of the box: http://upload.ozbargain.com/2009/12/21/3070_guylian_les_excl…
Damn, was going to post this. Beat me to it.
