Coles Group boss Steven Cain believes the supermarket chain has hit the “sweet spot” with its widest range of items at low prices and groceries readied for click and collect pickup in under an hour as the battle for consumer convenience ramps up.

The supermarket chain has shaved 30 minutes from its click and collect boot delivery service with the launch of its Coles’ Rapid Click & Collect at its next-generation supermarket at Southland in Victoria, where its largest collection point site sits, and new technologies are being trialled such as digital scales.
