I just saw this offer in my Commbank app, and there’s also an offer at David Jones for $15 cashback when you spend $100 or more.
Screenshot of the offers.
Spend $30+ on your next order with DoorDash and receive a promo code for up to 50% off. Minimum order value of $30, maximum discount of $15. Expires 31/12/2024. Offer can only be claimed once. Other fees apply. Not available on orders with alcohol. T&Cs apply.
FYI
A lot of fraud has been reported on Doordash accounts over the last couple of weeks.
I was warned a couple weeks back then surely enough i had over $300 of orders taken from my account!
