231. No merchant, manufacturer or advertiser may, by any means whatever, advertise goods or services of which he has an insufficient quantity to meet public demand unless mention is made in his advertisement that only a limited quantity of the goods or services is available and such quantity is indicated.
The merchant, manufacturer or advertiser who establishes to the satisfaction of the court that he had reasonable cause to believe that he could meet public demand or who offered the consumer, for the same price, other goods of the same nature and of an equal or greater cost price is not guilty of any infraction of this section.
