Saw this little gem in the Westpac app. Works on both a normal debit / credit card.
Spend $40 @ Crust Pizza for $15 cashback.
Crust Pizza currently has an offer for 2 XL Signature pizzas for $40 pickup (no code required).
Brings it down to $25 for two pizzas. Not bad at this price.
Im not sure if im getting stronger but the last time i ordered from crust the box was very light, im thinking they are cutting down on toppings
