According to our son who lives in Shanghai,China developed a very stong home delivery service capabilty over the last decade. The normal home food delivery he says is 20 mins. Even in the depth of the crisis, this apparently did not extent much beyond 40 mins. It was a vital tool in managing a full lock down.
We will not be able to match this but can ramp it up. For instance, M&S have just announced a deal for Deliveroo to deliver their Essentials range vis BP petrol station drop offs. M&S have been caught out becuase their deal with Ocado does not properly start until September.
