The Wine Collective is having a 'Christmas in July' sale, offering 1 free bottle when you buy 5, or 2 free bottles when you buy 10, from a selected range.
Included is the 2017 Grant Burge Filsell Shiraz. Simply add 6 bottles to your cart, and the price will be reduced to $159.95 for 6 bottles ($26.66/bt), plus shipping. New users should be able to use a referral to score $20 off this price, bringing the cost of 6 bottles down to $139.95 ($23.33/bt), plus shipping. Don't forget the 8.8% cashback from Cash Rewards to bring this down even further.
Free shipping for over $150 would be perfect!
