As of 2015, an annual Amazon Prime membership costs $99. A key benefit of the Prime service is free two-day shipping on many Amazon purchases.
Amazon Prime memberships offer a number of additional benefits to shoppers as well. Members can store an unlimited number of digital photos on Amazon's servers and have access to an extensive collection of advertising-free music. Streaming video is also included in Amazon Prime, allowing members to watch a number of movies and TV shows for no additional fee.
Certain groups of customers may qualify for reduced pricing and special offers on Prime memberships. For example, students enjoy a six-month free trial of two-day shipping and other Prime benefits and then pay 50 percent of the full membership price when the trial period ends.
