Saw some previous love for Powell & Son's wines this time last year so thought to share.

Coming in with two corkers of a wine, Vinomofo have the 2020 GSM at $12.50 a bottle (RRP $30) and the 2020 Blend Shiraz at $19.90 per bottle (RRP $80).
Free shipping till midnight & plenty of first time codes to use.
Be sure to use a referral code to help a fellow OzBargainer out ($25 off your first order, $25 for the referee).
Got the 2019 GSM last time around, it was awesome.
Ordered a dozen of this 2020 release, thanks for posting.
