She informs you that the industry gross profit percent in the retail drug industry declined fairly steadily for three years, which accounts for part of the decline. A second factor was the declining percent of the total volume resulting from the pharmacy part of the business. The pharmacy sales represent the most profitable portion of the business, yet the competition from discount drugstores prevents it from expanding as fast as the nondrug items such as magazines, candy, and many other items sold. Adams feels strongly that these two factors are the cause of the decline.
