Spend $20 on Amazon GCs with your Westpac card.
Get $2 bonus cashback.
Get a link that gives you 3 months of Amazon Prime or a $15 Amazon GC if you already have Prime.
Seems too good to be true?
Mod: $15 GC is this same/similar link as this deal, not a new promotion.
Make sure you purchase the 2% cashback Amazon GC. Challenge Link takes you to 1.75%
