For additional cashback, combine with either:
- AmEx Statement Credits Adore Beauty Spend $100 Get $20 (https://www.ozbargain.com.au/node/633432), or
- (credit to adelee) get 25% off for purchase between $10 and $2,000 using Klarna (in the form of Klarna making the fourth and final payment) (https://www.adorebeauty.com.au/klarna.html)
To earn the full $20 cashback, spend at least $122.22.
My purchase tracked GST-inclusive (despite SB's stipulation), which implies the minimum spending is $111.11 instead (YMMV).
