This seems to be a repeat of the 2011 Thorn Clark Terra Barossa Shiraz deal offered in May.

While the rrp is $19/bottle from the producer, $15/bottle seems to be the market rate.
Good reds for $10/bottle are alright by me though! Less if you haven't scored a first time referral bonus yet.

seriously,with the 2011 barossa reds, even big brands like penfolds had hard time making their 2011 wines, this is cheap but don't throw your money away like that, save it and buy something else. you can always search for good vintages on the search engine to make your money worth.
there are a few "mofo" deals that is more worthy than this.
