S.C. Code Ann. § 11-35-4840: Cooperative use of supplies or services.

Any public procurement unit may enter into an agreement independent of the requirements of Articles 5 and 15 of this chapter with any other public procurement unit for the cooperative use of supplies, services, or information technology under the terms agreed upon between the parties; provided, that such cooperative use of supplies, services, or information technology shall take place only when the public procurement units have good reason to expect the cooperative use to be more cost effective than utilizing their own supplies and services.
