The bonds may be sold by the Department of Agriculture and Industries from time to time in series. Each series of the bonds shall be sold at competitive bid and at such price or prices and at such time or times as the commissioner may consider advantageous. Bonds sold by competitive bid shall be sold, whether on sealed bids or at public auction, to the bidder whose bid reflects the lowest effective borrowing cost to the Department of Agriculture and Industries on the series of bonds being sold; provided, that if no bid acceptable to the commissioner is received, he or she may reject all bids. Summary notice of each such sale shall be given by publication in either a financial journal or a financial newspaper published in the City of New York, New York, and also by publication in a newspaper published in the State of Alabama which is customarily published not less often than three days during each calendar week, each of which notices must be published at least one time not less than 10 days prior to the date fixed for the sale or, in the event no bid acceptable to the commissioner is received at any such sale and the bonds so offered are thereafter reoffered on the same terms and conditions, not less than five days prior to the date fixed for sale. Neither a public hearing nor consent of the state Department of Finance or any other department or agency shall be a prerequisite to the issuance of any of the bonds.
