Found this hack which is a 20% saving on Coles gift cards.
- Add a $100 gift card to cart
- Add a $25 gift card to cart
- Apply code: EXCLUSIVEOFFER at checkout
- $125 worth of gift cards for $100
- This is a 20% saving which will be good for grocery shopping :)
Also works for other gift cards too.
Edit: Works on Website and In-app. Just use the link :)
Edit2: Looks like they've caught on and stopped it
Mod: Note this code was not designed for gift card purchases and was rectified by Target shortly after posting.
