First, I would never have cut FedEx before Christmas. This was a huge mistake since it limits their shipping compacity. Yes UPS and USPS can help but they should have waited till after Christmas. Second, doing big changes like 1-day shipping nationwide for Prime members should have been tested during an offseason to make sure it can work smoothly. We implemented software on October 15th and it was a disaster. It was good we did it early so we could catch it but man was that tough!
