Abstract: A system and method for contemporaneous and combined in-store shopping among multiple individuals uses: a central server that is in communication with a database storing information associated with products located within a physical store (in-store products); and a plurality of mobile devices, with each mobile device being located within the physical store and in communication with the central server. A communication to the central server from one of the mobile devices initializes a combined shopping session in which two or more mobile devices of the plurality of mobile devices located within the physical store are used to scan in-store products. Information associated with each in-store product scanned by the two or more mobile devices is retrieved from the database and added to one of a plurality of individual shopping transactions. The information within the plurality of individual shopping transactions is subsequently combined into a single, combined shopping transaction.
