(Reuters) – Amazon.com Inc told customers on Thursday that the annual membership fee for its Prime shipping and media streaming service would go up to $99 from $79 next week, the first time it has increased the price since the service began in 2005. Even as fuel and transportation costs have increased, the price of Prime has remained the same for nine years, Amazon told Prime members in an email. Amazons Prime unlimited two-day shipping and online streaming of movies and television shows is considered instrumental to driving purchases of both goods and digital media.
