Amazon started free two-day shipping for its members in 2005. At the time, the program was known as Amazon Prime, and subscribers to that service enjoyed free two-day shipping on all eligible orders. Over the years, Amazon has expanded the Prime program to include additional benefits, such as streaming video and digital products like music and books, and the free two-day shipping was included for all Prime members. To qualify for free two-day shipping, customers simply need to select items that are eligible for the service and have them shipped to an address within the two-day shipping region.
