All4Cellular via eBay offers the OtterBox Defender Case for iPhone 3G / 3GS in Black for $8.99 with free shipping. That's $4 under our October mention and the lowest total price we could find by $4. (We saw a refurbished unit for $2 less a week ago, since expired.) It features openings for the camera lens, dock connector port, and home button. Deal ends May 4 at 3:41 pm ET.
