Spotify offers its Premium for Family members a Google Home Mini for free. (Not a member? You can sign up here for $14.99 per month.) That's a savings of $49 and easy way to fill one of the six device slots that come with a Premium for Family plan. Deal ends December 31; devices must be redeemed by January 15, 2019.
