Customers can buy a GoPro (NASDAQ: GPRO) camera in any one of 45,000 retail outlets globally. While this a great convenience for its consumers, it has been a significant supply chain challenge for GoPro. In late 2015, the company overestimated demand for some of its HERO4 cameras and didn't respond fast enough when the cameras weren't selling as expected. This issue has led to reduced revenues, significant write-offs, and contributed to the stock price drop-off of almost 80% since September 2015.
