Previously we predicted that the iPhone 5C would be available at no cost during Black Friday 2013. I suspect that some retailers will be going after the Android crowd with similar offers during Black Friday 2013. On the devices like the Samsung galaxy S4 will be available at no cost, but I wouldn't be surprised to see them drop as low as $50-$100 during Black Friday sales.
The Galaxy S4 is more like compete directly against the iPhone 5S than the iPhone 5C. In that respect it will command a price premium but there is a chance device might be available for free from some retailers. Some wireless carriers have already off the device for under $150.
We expect to hear more on Black Friday sales any week now with October already at its midpoint. Typically Black Friday circulars begin leaking in going official at the end of October or beginning of November.
