Apple seems to be simplifying its range of accessories for its older iPhones ahead of the iPhone 6 launch on Friday. As shown above, Apple has removed every color of iPhone 5s case apart from black from its website. Although it is strange for Apple to reduce its potential for accessory sales (given that it still sells the iPhone 5s for only $99 on contract and many 5/5s models are out in the world), it is seemingly focusing on its new range of iPhone 6 and iPhone 6 Plus leather and silicone cases instead.
Apple did not offer plastic case options last year, although they appear to have proved popular. iPhone 6 cases are now backordered for several weeks. For iPhone 5s owners, it may be possible to find discounted cases at other retailers. AT&T currently has the color (RED) leather case on a 50% clearance sale, for instance.
