For new customers with a 2-year contract agreement only, Sprint offers the Apple iPhone 5c 16GB Smartphone for Sprint in five colors for free with free shipping. (Existing customers aren't eligible.) That's tied with last week's mention and the best price we've seen for the iPhone 5c. (It's also a current low by $99.) Alternatively, get the 32GB version for $99.99 with free shipping. That's the lowest total price we could find by $99. 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 dual microphones.

Sprint also offers new customers the Apple iPhone 5s 16GB Smartphone for Sprint in Gold, Silver, or Grey for $99.99 with free shipping. Alternatively, get the 32GB version for $199.99 or the 64GB version for $299.99, both with free shipping. That's tied with last week's mention and the lowest total price we could find by $99. It has the same specs as above but also offers Apple's new A7 processor package, billed as the first 64-bit smartphone chip. Other features include a Touch ID fingerprint reader built into the home button, M7 motion coprocessor, 5-element lens with f/2.2 aperture, True Tone flash, and 30 fps video shooting (120 fps shooting at 720p slow motion playback).
