N.J. Stat. § 56:8-107
The Legislature finds and declares that during emergencies and major disasters, including, but not limited to, earthquakes, fires, floods or civil disturbances, some merchants have taken unfair advantage of consumers by greatly increasing prices for certain merchandise. While the pricing of merchandise is generally best left to the marketplace under ordinary conditions, when a declared state of emergency results in abnormal disruptions of the market, the public interest requires that excessive and unjustified price increases in the sale of certain merchandise be prohibited. It is the intention of the Legislature to prohibit excessive and unjustified price increases in the sale of certain merchandise during declared states of emergency in New Jersey.
