Amazon Said Prime Membership Price May Increase $20-$40

Amazon.com may raise the price of its Prime membership by up to $40 for U.S. customers, the company said during its quarterly earnings call. Amazon's Prime membership is an annual subscription that gives frequent shoppers "free" two-day shipping on any item sold through Amazon or one of its affiliate sellers. Prime members also gain access to Amazon's Kindle e-book library-lending program and the Prime Instant Video service, which contains a collection of movies and TV shows that members can stream for free. Membership currently costs $79 per year, and the company hasn't increased the price in nearly a decade.
