To me, Prime’s promise of two-day shipping is more of an added bonus to Prime Video and stuff like Fallout. But it’s become an expectation, leading other retailers like Walmart and Target to roll out faster shipping options of their own.

Now, Amazon says its deliveries are getting even faster, announcing that it delivered over 2 billion items the same or next day to Prime members during the first three months of 2024, breaking its record for 2023. The company says it delivered almost 60 percent of Prime orders the same or next day in 60 of the biggest metropolitan areas in the US.

If you buy from Amazon, have you noticed any differences lately? Same-day and next-day options seem to be more widely available, but it’s hard to tell how that applies to different items in different places or whether the associated costs are worth it based on reports of warehouse injuries and workers organizing for better conditions.

The control Amazon has over shipping and fulfillment has helped make it the target of a lawsuit from the Federal Trade Commission. The agency alleges Amazon engages in anticompetitive behavior by unfairly limiting which sellers are eligible for Prime shipping and coercing companies into using its fulfillment services. Amazon claims that the FTC’s efforts could result in “slower or less reliable” Prime shipping for customers.

In 2019, Amazon said it was spending billions to build up an in-house fulfillment operation covering planes, trucks, drones, and robots to rival FedEx and UPS and enable these one-day-or-less deliveries. And last year, it introduced a program that allows sellers to ship their products directly from factories — regardless of whether they’re going to one of Amazon’s many warehouses.
