For the purpose of providing blind persons with remunerative employment, enlarging the economic opportunities of blind persons, and stimulating blind persons to greater efforts in striving to make themselves self-supporting, the commission shall administer and operate vending facilities programs pursuant to the federal Randolph-Sheppard Act, as amended, 20 U.S.C. 107 et seq. Blind persons licensed by the commission pursuant to its rules and regulations are authorized to operate vending facilities in any federally owned building or on any federally owned or controlled property, in any state-owned building or on any property owned or controlled by the state, or on any property owned or controlled by any county, city, or municipality with the approval of the local governing body, when, in the judgment of the director of the commission, such vending facilities may be properly and satisfactorily operated by blind persons. With respect to vending facilities in any state-owned building or on any property owned or controlled by the state, priority shall be given to blind persons, except that this shall not apply to the Game and Parks Commission or the University of Nebraska. This priority shall only be given if the product price in the bid submitted is comparable in price to the product price in the other bids submitted for similar products sold in similar buildings or on similar property and all other components of the bid for a contract, except for any rent paid to the state, are found to be reasonably equivalent to the other bidders.
