AutoZone, Inc., the automotive parts retail chain, has agreed to revise its business practices, and to pay $47,500 to the State, after a joint investigation by the New Jersey Division of Consumer Affairs Office of Consumer Protection and the State Office of Weights and Measures revealed numerous merchandise pricing violations. The investigation, undertaken early last year, found that seven AutoZone stores in Newark, Carteret, Elizabeth, Linden, Flemington, and Plainfield, failed to plainly mark the total selling price on some merchandise.
