Best Buy is having a special sale for the contract price of the iPhone 5c. If you buy the iPhone 5c between October 3rd (yesterday) and October 7th, it will cost $50 with a two-year contract. This can be considered the fastest discount for an Apple product that I am aware of. It is believed that the iPhone 5s has sold around 3.4 times as much as the iPhone 5c. This is because the iPhone 5s has a faster processor speed and comes with the Apple Touch ID fingerprint scanner.
