Ending today, Groupon offers the factory-refurbished Ooma Telo VoIP Phone System for $69.99. Coupon code "EXTRA" drops it to $62.99. With free shipping, that's $2 under last week's refurb mention and the lowest total price we've seen without a required contract. (It's the best deal we could find by for a refurb today by $7.) It offers unlimited calling to any number in the US via your broadband Internet connection. It features caller ID and a landline backup option. A 1-year Ooma warranty applies.
