Just found it in my Rewards section.
Go to the For you section in the Commbank app, usually the bottom right.
Then select Rewards and it should be there. It may be a different amount given it is targeted.
I am going to wait to stack this with a cashback deal given it's an entire month to spend as I've done this before.
Instructions from prior deal regarding payment, thanks to V13tbargain!
1) Pay with your eligible CommBank debit or credit MasterCard or StepPay and tap or select credit.
2) Get cashback into your account, typically paid within 14 business days.
3) Spend by 1 March
Thanks for this.
My offer was better - "Get $10 Back When You Spend $50 or More"
