(a) It shall be the duty of the Department of Administrative Services, in the purchase of and in contracting for any supplies, materials, equipment, and printing, to give preference as far as may be reasonable and practicable to such materials, supplies, equipment, and printing as may be manufactured or produced in this state. It is the intention of this subsection that the state use, insofar as is practicable, Georgia products and Georgia labor; provided, however, that in giving such preference no sacrifice or loss in price or quality shall be permitted; and provided, further, that preference in all cases shall be given to surplus products or articles produced or manufactured by other state departments, institutions, or agencies, which are available for distribution.

(b) Vendors resident in the State of Georgia are to be granted the same preference over vendors resident in another state in the same manner, on the same basis, and to the same extent that preference is granted in awarding bids for the same goods or services by such other state to vendors resident therein over vendors resident in the State of Georgia.
