You need to distinguish between grocery delivery and food/meal delivery.

In Australia, the two primary grocery outlets, Coles and Woolworths, already had online ordering and delivery. The use exploded with the lockdown but they have ramped up.

The cost for a delivery depends on the value of the order for Woolies and on time of day and delivery window for Coles but is of the order of $10-$15.

A lot of people have moved to the services to avoid going to the supermarkets, and many won't return to physical shopping for the weekly groceries.

The food delivery services are a bit different, there's the widely spread existing services like Dominos etc, but then there's the Uber Eats/Doordash etc. For the moment, the Eats/doordash people are screwing the restaurants, but they're starting to also charge more to the customers.
