Found this in First Choice Liquor, Oxley, QLD.
The 2016 St Andrews imperial reserve Cabernet Sauvignon earned a couple of gold medals and was originally priced at $6 a bottle.
On special at 6 for $26.
Note: 2016 vintage was found in Oxley, QLD store. not sure about other stores.
I've tried both 2016 and 2017. 2017 isn't far behind.
Note that the link goes to the 2017 version on the website whereas the deal is for the 2016 which may have limited stock.
The First Choice store add in your post says 2017 vintage, not 2016. It was the 2016 vintage that won the gongs in Melbourne. It sold out pretty much instantaneously, not surprising at $6. The 2017 is reputedly nowhere near as good, although I must admit I haven't tried it. Still busy with the 2016 .. :-) .. !!
