JemJem offers the refurbished Apple iPhone 6S Plus 16GB 4G LTE Smartphone for AT&T
(no contract) in four colors (Silver pictured) for $377
for shipping. That's the best deal we could find for a no-contract refurb for AT&T by $46 and the lowest total price we've seen for the 16GB model with no contract. (For further comparison, we saw an unlocked refurb for $420 in November.) It features a 5.5" 1920x1080 (1080p) Retina HD display with 3D touch, A9 chipset, 2GB RAM, 16GB flash storage, 12-megapixel iSight camera with 4K video recording, 5-megapixel FaceTime HD camera with Retina Flash, 802.11ac wireless, Bluetooth 4.2, second-generation fingerprint sensor, and iOS 9.
A 30-day JemJem warranty applies. Note that it comes with a non-OEM charger.
