Hi all. Yes the Semillon is very good for the $80/dozen. As I said before, ignore the 'rrp' & consider it is worth $80.
If you subtract that $80, maybe from their Fine & rare selection:
St Hallett Old Block Barossa Shiraz 2012 or Wolf Blass Black Label Cabernet Sauvignon Shiraz Malbec 2012 both @ $119.99 = ~$39.99 though this calculation is only for 1 bottle.
Or Penfolds Bin 389 South Australia Cabernet Shiraz 2016 or Vollereaux Champagne Cuvee Marguerite Brut each @$99.99 = ~$19.99 plus whatever else you may be tempted to sample.
Or anything else that takes you to the $100 spend in 1 - 3 or 12 bottles eg a mixed dozen.
It only 'works' if you buy the minimum spend & just do the simple subtraction/mental gymnastics. You won't save more by buying more, just play the deal & you can get something good that you might not otherwise try.
