An association may use or employ any of its facilities for any purpose, provided the proceeds that arise from such use and employment shall go to reduce the cost of operation for its members. The cannabis products that are handled for, or the services, machinery, equipment, or supplies or facilities that are furnished to, nonmembers shall not, however, exceed in value the cannabis products that are handled for, or the services, merchandise, or facilities that are supplied to, members during the same period.
