A computer program product for co-locating subject-related persons, the computer program product comprising a computer readable storage medium having program code embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, and wherein the program code is readable and executable by a processor to perform a method comprising:

• determining, by a first positioning system on a first communication device, a first location of a first person who is using the first communication device, wherein the first location is a location within a physical retail store at which a particular type of product is displayed;
• receiving, by a message receiver on the first communication device, a message from a second positioning system on a second communication device describing a second location of a second person, wherein the second person has been predetermined to have used a product from the particular type of product that is displayed at the first location;
• transmitting, by a message transmitter on the first communication device, a message from the first communication device to the second communication device requesting that the second person meet the first person at the first location to discuss one or more products being displayed at the first location;
• receiving, by the message receiver on the first communication device, a responsive message from the second communication device indicating an agreement from the second person to meet the first person at the first location;
• and
• transmitting, from the message transmitter on the first communication device to the second communication device, navigational directions from the second location to the first location.

A communication device comprising:

• a first positioning system;
• a message receiver;
• and
• a message transmitter;
• wherein the first positioning system on a first communication device determines a first location of a first person who is using the first communication device, wherein the first location is a location within a physical retail store at which a particular type of product is displayed;
• wherein the message receiver on the first communication device receives a message from a second positioning system on a second communication device describing a second location of a second person, wherein the second person has been predetermined to have used a product from the particular type of product that is displayed at the first location;
• wherein the message transmitter on the first communication device transmits a message from the first communication device to the second communication device requesting that the second person meet the first person at the first location to discuss one or more products being displayed at the first location;
• wherein the message receiver on the first communication device receives a responsive message from the second communication device indicating an agreement from the second person to meet the first person at the first location;
• and
• wherein the message transmitter on the first communication device transmits, to the second communication device, navigational directions from the second location to the first location.
