§15-598.5.
   
   (a) In addition to the penalties provided in this act, any person
   injured by any violation, or who shall suffer injury from any
   threatened violation of this act, may maintain an action in any court
   of equitable jurisdiction to prevent, restrain or enjoin such
   violation or threatened violation. If in such action a violation or
   threatened violation of this act shall be established, the court shall
   enjoin and restrain or otherwise prohibit, such violation or
   threatened violation and, in addition thereto, shall assess in favor
   of the plaintiff and against the defendant the cost of suit. In such
   action if damages are alleged and proved, the plaintiff in said
   action, in addition to such injunctive relief and costs of suit, shall
   be entitled to recover from the defendant the actual damages sustained
   by him.
   
   (b) In the event no injunctive relief is sought or required, any
   person injured by a violation of this act may maintain an action for
   damages alone in any court of general jurisdiction, and the measure of
   damages in such action shall be the same as prescribed in subsection
   (a) of this section. Provided this act shall not authorize suits or
   actions against newspapers, radio broadcasters, or other advertising
   agencies through which such advertisements are published, broadcast or
   otherwise made.
   
   (c) Evidence of advertisement, offering to sell, or sale of
   merchandise by any retailer or wholesaler at less than cost to him,
   shall be prima facie evidence of intent to injure competitors and to
   destroy or substantially lessen competition.
