Gentlemen:

     In connection with the Registration Statement on Form S-8 (the
"Registration Statement") relating to a proposed public offering of 1,500,000
shares of common stock, par value $.10 per share, of Best Buy Co., Inc., a
Minnesota corporation (the "Company"), pursuant to the Best Buy Co., Inc. 1994
Full-Time Employee Non-Qualified Stock Option Plan, we, as counsel for the
Company, have examined such corporate records and other documents, including the
Registration Statement, and have reviewed such matters of law as we have deemed
relevant hereto, and, based upon such examination and review, it is our opinion
that all necessary corporate action on the part of the Company has been taken to
authorize the issuance and sale of 1,500,000 shares of Common Stock by the
Company, and that when issued and sold as contemplated in the Registration
Statement, such shares will be validly issued, fully paid and nonassessable.

     We hereby consent to being named in the Registration Statement, and in the
Prospectus related thereto, as counsel for the Company who have passed upon
legal matters in connection with the issuance of the Common Stock.  We further
consent to the filing of this opinion as an exhibit to the Registration
Statement.

                                        Yours very truly,



                                        ROBINS, KAPLAN, MILLER & CIRESI
