YouBuyRite via eBay offers the refurbished
Unlocked Apple iPhone 7 128GB Smartphone in several colors (Jet Black pictured) for
$489.99 with
free shipping. That's $25 under our mention from three days ago and the lowest price we've seen for it unlocked in any condition. (It's also at least $259 less than you'd pay for a new, unlocked device.)
Note: A 30-day warranty applies, but it's not clear who backs it.
