Best Buy offers the OtterBox Defender Case with Holster for iPhone 4 / 4S in Yellow/Gray, model no. 63-1574-05-BB, for $19.99 with free shipping. That’s a buck under our mention from last March and the lowest total price we could find for any color by $9. (For further comparison, we saw an OEM unit for $5 less in December.) Sales tax is added where applicable. It features a clear protective membrane for the touchscreen plus openings for the camera lens, dock connector port, and home button.
