Walmart is going to be selling the iPhone 5s and the iPhone 5c for lower prices than other retailers. Walmart is going to be charging $79 for the iPhone 5c and $189 for the iPhone 5s. Other retailers are charging $99 and $199, respectively. The 5c can be pre-ordered from Walmart starting today, but there are no pre-orders for the 5s. Smartphone trade-ins at Walmart are starting on September 21st so it may be worth waiting until then if you are planning to upgrade through Walmart.
