Pangea Deals via eBay offers the refurbished Apple iPhone 6 16GB No-Contract Smartphone for AT&T in Space Gray, Gold, or Silver for $429.99 with free shipping. That's tied with our mention from three weeks ago as the lowest total price we've seen for a no-contract iPhone 6. (It's a current low for a refurb by $95 and $219 under the best price for a new unit.)
