As per T&C, it only applies to new customers (whose with a new account or an existing account which has never bought before).
Looks like a good deal when they have EOFY sale happening, tested can stack with 10% auto deliver and 15% new signup
Purchased a 10kg Black Hawk Fish and Potato dog food.
Original price: 88.79
Current price: 71.03
After Auto Deliver: 63.93
After 15% signup offer: 54.34
If you factor in 5000 reward points ($25) can be used in Woolworths, final price is 29.34.
Is this for existing customers as well?
