As used in this subchapter:
"Adequate and reasonable competition" means the amount of vendors solicited based upon the number of vendors available and the value or price of the goods, service, or construction. Because of variations in circumstances, it is not possible to define what is adequate and reasonable competition for every small procurement. However, in general, the more vendors there are that can meet the needs of the agency, or the higher the price of the goods, services, or construction, then a greater number of vendors should be solicited.
