Section 3(2) provides that if goods are sold and delivered to minors or those mentally incapacitated the minor will be liable to pay a reasonable price if the goods are "necessaries". Necessaries are goods suitable to the persons' condition of life and actual requirements at the time of contracting. Under sections 6 and 7, concerning specific goods that perish, a contract is "void" where they perish before and avoided where they perish after contract formation. (See Mistake (contract law)). Under section 8(2) the "price" is a money consideration given in exchange for property in goods. If the price, or means to ascertain a price, is not agreed, the buyer will be required to pay a reasonable price.
