Walmart offers the refurbished Apple iPhone 5s 16GB Prepaid Smartphone for Straight Talk in Space Gray or Silver bundled with a 30-Day Service Plan for $198 with free shipping. That's a buck less than last month's mention of a new phone without a service plan and the lowest total price we've seen for the Straight Talk version of this phone in any condition. (It's also $56 under the best price we could find for a refurbished phone without the plan today.) It features a 4" 1136x640 Retina display, 8-megapixel rear camera, front camera, 1080p HD video recording, Bluetooth, WiFi, and iOS 7.
