12x Kooks Barossa Valley Shiraz 2012 for $106.80 ($8.90 a bottle)
This red is a full-bodied blend of Barossa Valley, McLaren Vale and Coonawarra Shiraz, usually selling for between $15 and $20 a bottle. In other words, during this deal at VinoMofo, you're basically getting double the wine for just $20 more than what a case of six would typically have cost you otherwise.
Currently Dan Murphy's also has the Kooks Shiraz on an online only offer for $12 a bottle, which means that they've got the next best price at $144 for the dozen. Look at prices elsewhere and you'll see this premium red starting from $180 for the dozen.
