they put about $550 cash back into my account during the 6 month period. ($550 free money )
ERD mentioned about american express and will have some details on it
What is everyone using to max their points, rewards, cash back etc.
Currently shop at Woolies ( perth ) so do use the Rewards card and do get Qantas FFP with that.
