Frustrated with having the postman deliver parcels when no one is at home? That may soon be a thing of the past, with Singapore Post (SingPost) set to launch an automated delivery locker system that lets customers receive their parcels round the clock. Dubbed PopStation (Pick Own Parcel Station), the free service has been available since last month to select users of its vPost service, which helps online shoppers buy items from overseas. SMU Associate Professor of Marketing (Education) Seshan Ramaswami said that the new service will have "a ready set of consumers" as it meets a pressing need of many Singaporeans. "As with any retail service, a critical factor is the location of the PopStations. If they are easily accessible to most consumers, then the service will do very well," he said.
