Amazon pushed harder on fast delivery. Now FedEx and OneRail are answering with same-day shipping at scale. The new partnership gives retailers access to two-hour windows, end-of-day delivery, and near real-time tracking, using existing store networks instead of building a whole new infrastructure stack. OneRail says it covers 99% of the U.S. through 1,000+ carriers and 12 million drivers. Once people get used to speed somewhere, they start expecting it everywhere.
