YouBuyRite via eBay offers the refurbished Unlocked Apple iPhone 6 Plus 128GB GSM Smartphone in Space Gray for $329.99 with free shipping. That's tied with last week's mention as the cheapest unlocked iPhone 6 Plus 128GB we've seen. (It's $40 under the lowest price we could find for a refurb unit elsewhere.)

Note: A 30-day warranty applies but it's unclear who backs it.
