What is Instant Grocery? Instant grocery delivery is a service model where groceries and household items are delivered to the customer’s doorstep almost immediately after the order is placed. These services typically operate through dark stores (small, local fulfillment centers not open to the public) or tie-ups with local supermarkets. https://git.louhau.edu.mo/Bfsi21/Finance/wiki/Instant+Grocery%3A+The+Rise+of+On-Demand+Food+Delivery+Services.-
