Deal is two year purchase contract you make monthly payments and you get half the payment credited back. Yes, it is a two year commitment to keep your line or you will pay full price remaining. Still you get a great phone for half off. Deal is for Moto Z and Moto Z Force at Verizon and Best Buy. Time span is January 20 till February 20. Best way to buy is on Verizon website, that way you don't have to deal with misinformed sales people who would rather take advantage of you anyway.
