Third-Party
Couldn't see this previously posted so not sure how widely known it is.
If you haven't purchased a gift card on shop back before you can get 100% ($5) cash back on a range of $5 gift card purchase.
Should show up at the top of the page as "New Customer Offer"
Range includes: Uber, Amazon, Coles, Woolies, Target, Kmart.
One time use.
You can only do this once, so choose wisely. Attempting to buy another card gets you the 'This deal isn’t available to you, but there are many others to choose from!' message and minimum withdraw amount is $10.
