The provisions of this section shall not apply to: (i) commodities when sold for immediate consumption on the premises where sold; (ii) vegetables when sold by the head or bunch; (iii) commodities in containers standardized by law; (iv) commodities in package form when there exists a general consumer usage to express the quantity in some other manner; (v) concrete aggregates, concrete mixtures, and loose solid materials, including earth, soil, gravel and crushed stone, when sold by cubic measure; (vi) unprocessed vegetable and animal fertilizer when sold by cubic measure; or (vii) peanuts in large multiple bag lots being sold by cleaners or shellers to processors for further processing or repacking. The articles in clauses (i) through (vii) may be sold on a gross weight basis if agreed upon in writing by the mutual consent of the buyer and seller.
