The Evaluation Grid Method (EGM) has been developed in 1986 as an extension of Kelly's Repertory Grid Method to overcome the shortcoming of the conventional interview methods. The largest merit of EGM is that user's preference structure can be elicited as they are. However, as long as EGM is carried out in face-to-face mode, the number of participants is inevitably limited within a given research budget. Thus the interviewees are restricted by time, and interviewers have to conduct personal interview on an individual basis. This paper introduces EGM research on gas station preferences conducted by e-mail among voluntary participants.
