Amazon created the expectation of 2-day shipping. Now it needs to scale back. - Vox Free two-day shipping attracts customers. It also costs Amazon a lot of money. In less than two decades, Amazon single-handedly transformed the way we think about online shopping. Before Prime launched in 2005, two-day shipping was virtually unheard of — now more than 100 million people use the service, and they expect the things they order online to arrive at their doorsteps in 48 hours or fewer. There’s just one problem: Amazon, which has focused on obtaining customers at all costs for decades, seems to be looking for ways to cut down on shipping costs. In some cases, that means weaning Prime users off the near-instantaneous shipping they’ve come to expect.
