Today only, All4Cellular offers the refurbished OtterBox Defender Case with Holster for iPhone 4S in five colors for $9.99 with $2 for shipping. That's $9 under a new, factory-sealed mention from two weeks ago and the lowest total price we've seen for this case. (It's also $9 under the best price we could find for a new one now.) It features a clear protective membrane for the touchscreen plus openings for the camera lens, dock connector port, and home button.
