Earn 5% cashback on $100 and $200 Amazon gift cards on ShopBack when you link and pay with an eligible Westpac, Bank of Melbourne, BankSA or St.George credit or debit card.
The 5% cashback consists of the publicly available 2% rate on $100 and $200 Amazon gift cards plus an additional 3% for those who link and pay with an eligible card.
Interestingly, there appears to be no purchase limit listed for the bonus 3% cashback. However, you are apparently limited to five each of the $100 and $200 Amazon gift cards.
