The Amazon Prime membership may increase by $20 to $40 per year. Currently, Amazon Prime costs $79 per year and it has been this way for years. Amazon Prime includes free two-day shipping on physical goods and it offers unlimited streaming of TV shows and movies from Amazon Instant Video. Amazon said that the rise would be due to the rise in fuel charges and shipping costs. Amazon is “considering” the change right now and it may fall through. It is unknown how many Amazon users are signed up with Prime. Apparently, Amazon Prime members spend approximately twice as much compared to regular Amazon shoppers ever year.
