If you are referring to the wholly-owned subsidiary of Berkshire Hathaway and the oracle of Omaha, I have never seen a shop for them. I would love to do it as there is one close. Even as a shareholder of Berkshire Hathaway, I think they should be doing shops. See's Candy is another wholy-owned subsidiary of Berkshire Hathaway and they have shops done. However, each company is run independently. Buffet does not buy the companies to change what they are doing, but instead buys good companies with good management at an attractive price.
