This holiday season, it is estimated that 3 billion packages will be shipped in the United States. That makes about 800 million more packages delivered than last year. When you divided it into days, it means that 7.2 million more packages need to be shipped each day. This is an issue as the system might not have the capacity to handle.
With shipping, I let customers know beforehand of a possible delay. As an incentive we offer samples and free shipping in the U.S. It's imperative to be transparent with customers and e-commerce businesses can write a notice on their website.
