Oklahoma State University's University Store has a smart approach to fostering student loyalty: an expert technology department, OrangeTech, with free services like repair and 3D printing. Any student in need of computer repair or assistance can find a tech-savvy associate on hand. For 3D printing, customers pay a minimal charge for materials but nothing for the processing and expertise. OrangeTech’s services give University Store an edge over off-campus retailers — and inspire customer allegiance.
