Abstract: Embodiments of the subject technology provide a same day delivery system in an online marketplace. The subject technology receives, from a seller, data representing a window of time for which a pickup of a physical item occurs at a location of the seller for a delivery of the physical item to a location of a buyer. The subject technology determines a second location corresponding to a different delivery of a different physical item by a driver. The subject technology selects the driver, among a set of drivers, for delivery of the physical item where the driver is currently performing the different delivery of the different physical item when the driver is selected for the delivery of the physical item. Further, the subject technology adds the delivery in a queue of deliveries, the queue including the different delivery of the different physical item, for the driver during a particular day.
