Walmart Friday permanantly slashed prices on the iPhone 5S and 5C. 

The retail giant is now selling the 16 GB iPhone 5S for $99, down from $149. And the 16 GB iPhone 5C will be cut to $29 from $49. 

The reduced prices come as Apple and its partners might be trying to get rid of existing inventory before a fall launch of the iPhone 6. 

A recent report from the International Business Times claims that Apple has set a September 19 release day for the iPhone 6. 

Apple is expected to bring two models to market later this year, including a 4.7-inch iPhone, as well as a 5.5-inch phablet-sized version. The Business Times said the larger version may be delayed.
