As one of its daily deals, Amazon offers the Ooma Telo Free Home Phone Service for $74.99 with free shipping. That's the lowest total price we could find by $18 and the best price we've seen for a new unit in over a year. (For further comparison, we saw a refurb for $57 in November.) It offers unlimited calling to any number in the US via your broadband Internet connection. It features caller ID and a landline backup option. Deal ends today.
