The doorstep delivery platform is to expand to offer on-demand groceries ‘within minutes’ to customers Doorstep milk delivery platform DairyDrop is launching an on-demand grocery service in response to “hundreds and hundreds” of emails from its customers. The company is to expand its offering by establishing dark stores in Manchester and London, and has recruited 50 couriers to make deliveries “within minutes” to areas surrounding the units. DairyDrop works with several UK dairy suppliers to connect them with consumers seeking regular milk rounds. However, for its on-demand venture, the company will be sourcing and selling a broader range of convenience products directly to the consumer.
