Cal. Food and Agricultural Code § 3105

(a) The Legislature finds and declares that district agricultural associations, county fairs, citrus fruit fairs, and the California Exposition and State Fair, collectively known as the network of California fairs, are a valuable community resource, and recognizes that local businesses and local communities make valuable contributions to fairs that include direct and indirect support of fair programs. The Legislature further finds and declares that local businesses often provide opportunity purchases to local fairs that, for similar things available through the state purchasing program, may be purchased locally at a price equivalent to or less than that available through the state purchasing program. (b) In order to make opportunity purchases, a fair shall develop applicable policies and procedures. (c) As used in this section, “opportunity purchases” means purchases made locally, either individually or cooperatively, at a price equal to or less than the price available through the state purchasing program on or off state contract.
