I ordered the case-mate barely there case. It's $30 but coupon code tough drops it to $24. Ordered on Saturday and received Wednesday (before iPhone 5 was released). Really like te case - smooth but not slippery, and the front extends just enough to protect the screen without wrapping around the front.
