A case of 2006 Brands Laira Coonawarra Shiraz from Jacks Wine $167.88 - Buckscoop Cashback
Its a triple gold medal winner and generally the Brands Laira wines have a bunch of medals between them so the probability that you'll end up with a very drinkable wine is high. Its also a 94/100 Halliday rating
Cost of the case is $167.88 or $13.99 a bottle. Once cashback is taken into account the cost will be $159.63 or $13.30 per bottle.
