Works well with the free Dashpass from this great deal.
Even better if you shop from Coles, which seems to match in-store pricing and weekly specials on Doordash.
With free delivery and 10-12% service fee, you would get approximately 30% off a $40 order delivered to your doorstep. Pretty good value considering the rising cost of living.
