2.3 The Salvation Army, a religious nonprofit organization, operates charity and thrift stores called Sally’s. When a donor contacts the organization, it sends a truck to pick up the goods. The Salvation Army rejects heavily used, broken, or soiled goods. The managers could hire a trucking company to pick up the donations, but instead they use their own trucks operated by their own employees. Why did the managers decide to vertically integrate rather than outsource their trucking needs?
