All4Cellular offers discounts on a wide selection of Otterbox cases and accessories. Plus, coupon code "OTTER10" cuts an extra 10% off. With free shipping, that's the best discount we've seen on such a wide range of Otterbox cases from All4Cellular. Choose from Apple, Blackberry, HTC, Motorola, or Waterproof cases.

A best bet is the refurbished OtterBox Defender Series Case and Holster for iPhone 5 in Black for $17.95 before the above coupon, $16.15 after. With free shipping, that's a buck under last month's mention and $15 under the lowest total price we could find for these items, new, purchased elsewhere. The case allows for access to all ports and buttons, and the holster clips on to your waistband or belt. No warranty information is provided.
