Warren Buffett, CEO of Berkshire Hathaway, recommends two Berkshire Hathaway subsidiaries: GEICO for auto insurance and Borsheim's for jewelry. He claims GEICO offers lower rates than other national insurers for a significant portion of drivers. Buffett also asserts that Borsheim's offers exceptional value due to its large volume and low operating costs, enabling them to pass savings onto customers. He encourages readers to explore GEICO's online or phone services and to contact Borsheim's for jewelry needs, emphasizing the potential for substantial cost savings.
