On February 2, 2005, Amazon introduced Amazon Prime. “For a flat membership fee of $79 per year, members get unlimited, express two-day shipping for free.” Jeff Bezos said that “two-day shipping becomes an everyday experience rather than an occasional indulgence.”
In April 2019 Amazon announced that one-day shipping would become the standard for Prime members. It expected to spend $800 million in one quarter on warehouses and delivery.
