CTCStore offers the Acase Superleggera Pro Fit Dual-Layer Case for iPhone 5c in Black for $12.95. That falls to $6.95 at checkout. With free shipping, that's $23 off list and the lowest total price we could find, although we saw it in Purple for about a buck less two weeks ago. This 2-layer case features a silicone skin and a polycarbonate shell. Deal ends October 5.
