Coles on DoorDash used to have 10% on top of their normal store price.
But I just checked it today and they add 5% on top - total of 15%.
The price increase appears for both the "Coles" and "Coles Local" stores.
Seems like the subsidy has dried up :(
This could be one for the ACCC Grocery enquiry.
Coles Plus @ $19pm offers free delivery for orders over $50 but at least you play Coles "normal" prices and get Flybuys in what you Order.
