YouBuyRite via eBay offers the refurbished Unlocked Apple iPhone 7 Plus 32GB Smartphone in several colors (Black pictured) for $519.99 with free shipping. That's $30 under our September mention and the lowest price we've seen for an unlocked iPhone 7 Plus. (It's the best deal we could find for a refurb today by $30.) Note: A 30-day warranty applies, although it's unclear who backs it.
