N.J. Stat. § 51:1-97

a. No person shall: (1) Sell or expose for sale less than the quantity represented of a commodity or service; (2) Take any more of the quantity represented of any commodity or service, when, as a buyer, he furnishes the weight or measure by which the commodity or service is determined; (3) Deliver or cause to be delivered less than the quantity or service represented of any commodity or service commonly sold by weight, measure, count or time; (4) Misrepresent the price of any commodity or service sold, offered, exposed, or advertised for sale by weight, measure, count, or time, or represent the price in any manner calculated or tending to mislead or in any way deceive a person; (5) Falsify, prerecord, issue or have in his possession a meter register, delivery ticket, invoice, bill or any document which contains a quantity representation recorded prior to the actual measurement at the time of delivery of the commodity; or (6) Preprint, postprint, alter, or have in his possession a credit card, receipt or original containing a false representation of the quantity or value of petroleum products delivered. Any person who violates the provisions of this subsection shall be liable for the first offense to a civil penalty of not less than $50.00 nor more than $100.00, and for a second offense to a civil penalty of not less than $100.00 nor more than $250.00, and for each subsequent offense to a civil penalty of not less than $250.00 nor more than $500.00. b. No person shall be convicted of or assessed a civil penalty for a second or subsequent offense pursuant to this section unless the previous conviction: (1) Occurred no earlier than one year prior to the occurrence of the second or subsequent offense; and (2) Occurred at the same place of business as the second or subsequent offense. For the purposes of this subsection, "same place of business" means identical store or outlet. c. Nothing in this section shall be deemed: (1) to authorize or permit the imposition of penalties for a second or subsequent offense in conjunction with an adjudication of guilt based upon multiple counts or complaints arising from the same inspection, or (2) to mandate the imposition of penalties for a second or subsequent offense, if, in the discretion of the court, the imposition of a penalty for a first offense would be just and proper.
