Groupon offers the OtterBox Reflex Series Case for iPhone 5/5S in Blue for $9.99 plus $3.99 for shipping. That's the lowest total price we could find by $2, although we saw it for $4 less in another color in November. This two-piece case is made of polycarbonate and rubber and features an adhesive screen protector.

Also available is the OtterBox Commuter Series Case for iPhone 5/5S in Bolt for $11.99 plus $3.99 for shipping. That's the lowest total price we could find by $6, although we saw it for $6 less three weeks ago.
