A system and method for expediting fulfillments of online ordered dual-commerce available deliverables of networked supermarket deliverable providers (NSDPs), by a customer of a NSDP expedited service area (ESA) providing sequenced deliverable pickup fulfillments within specified limited-time periods, and/or by delivery fulfillments made to specific locations, as selected in a website or mobile application user interface associated with a NSDP accessible via a personal wireless communication (PWC) device or handheld PWC device. Designated ESAs and/or designated workstations or bays adjacent robotic deliverable fulfillment secure enclosures, located within, adjacent, or nearby, respective NSDPs provide deliverable pickup fulfillments more quickly to scheduled ESA-visit customers than NSDPs provide to non-ESA customers. A GUI may present categorized browsing of deliverables of a NSDP available for online ordering, purchasing and either or both dual-commerce fulfillments, an itinerary or schedule including one or more ESA-visit time-window(s), a map and/or navigational instructions and/or contextual-prompts facilitating ESA fulfillments.
