If there are meaningful differences in customer needs within segments which are presently not being met by current market segmentation, then there is need for possible sub- segmentation. For example, a ready food kitchen may go in for segmentation within such segment. It may go for office delivery, food for standing on the ground floor, and customers sitting with air-conditioned atmosphere on the first floor. Food remains the same, but prices differ. We may call it as ‘micromarketing’.
