Like the previous promotion (http://www.ozbargain.com.au/node/94618), get a free double pass to the Food and Wine show (valued at $66) and is being offered as part of the MyerOne special promotions.
Melbourne show dates: 7-10 June 2013
Sydney show dates: 28-30 June 2013
Sydney tickets are going fast but still decent selection of all dates for Melbourne.
2,500 double passes allocated for this promotion.
Edit - Code METRICON also seems to still be working. Good luck with getting the passes!
