Mobile Karma via eBay offers the refurbished, no-contract Apple iPhone 5 16GB Smartphone for Sprint in White for $299.99 with free shipping. That's $350 off and the best price we've seen for a no-contract 16GB iPhone 5. (For further comparison, it's also $220 under our last mention of a no-contract refurbished model from over a year ago.) It features an Apple A6 processor, 4" 1136x640 Retina display, 8-megapixel iSight camera, 1.2-megapixel FaceTime HD camera, 1080p video capture, 802.11n wireless, Bluetooth 4.0, and 1GB RAM.

Update: The price has dropped to $279.99.
