Walmart offers the refurbished Unlocked Apple iPhone 6s 64GB Smartphone for GSM Networks in four colors (Silver pictured) for $549 with free shipping. That's the best deal we could find for a refurb today by $51 and the lowest total price we've seen for an unlocked 64GB iPhone 6s in any condition. (For further comparison, we saw a new one for $700 four weeks ago.)
