Groupon offers the factory-refurbished Ooma Telo Free Home Phone Service for $59.99. Coupon code "EXTRA15" cuts that to $50.99. With free shipping, that's $6 under our refurb mention from two weeks ago and the lowest total price we've seen for this item without a required-at-activation subscription. (It's a current best for a refurb by $29 and $59 less than you'd pay for a new one.) It offers unlimited calling to any number in the US via your broadband Internet connection. Features include caller ID and a landline backup option. A 1-year Ooma warranty applies. Deal ends February 10.
