Personally, I always receive $5 cashback on $100 Spend while my wife receives $10cashback on $200 spend, even after ignoring the last 2 times to try and get better options!
Please Note: the cashback values vary with the minimum spend and is specific to each CommBank Yello Account Holder, so this offer is always Targeted.
How to claim:
Activate before you spend.
Pay with your eligible CommBank debit Mastercard or credit Mastercard or StepPay and tap or select credit.
Get cashback into your account, typically paid within 14 business days
Ours always $5 off $50 since the start, until last offer my partner one changed to $5 off $100 :(
