During the period of May 16-27, 1976, interviews were completed in Philadelphia and Boston, and interviews in Detroit were completed June 6-9. In the three cities, a total of 26 persons in 17 retail chains were interviewed, along with 17 people from 14 wholesale firms. In addition, 30 individual retail stores were visited, 10 in each city, and produce managers were interviewed in each store. It will be noted in Table 1 that one of the large national chains was contacted in more than one city. These were region or division offices responsible for stores in the particular market area. In several cases, the corporate offices of other chains were included in the interviews.
