The intent of the purchasing policies is to establish a framework so that purchasing activities for the District are carried out in a prudent and economical manner. Fundamentally, the objective is to purchase supplies and equipment from the qualified vendor who submits the lowest bid for products, which are equal or better than the specifications in the bid documents. The supplier who may be awarded the bid need not be the lowest bidder, but rather the lowest bidder for the quality, service, and quantity of items as specified. [Idaho Code 33-506 (1)]
