N.M. Code R. § 12.2.4.14
“Free gifts”:
B. It is an unfair or deceptive trade practice for a dealer to use the word “free” or words of like meaning and import when describing a gift or other item to be given to a customer who purchases a product or service if the selling price of the product or service is increased as a result of the “free” item or if the product or service can be purchased for a lesser price without the “free” item.
