Amazon.com Inc., the world’s largest Internet retailer, boosted the price of its Prime membership by 25 percent to $99 a year, the first increase since the service’s introduction nine years ago. The new Prime Fresh, a same-day local delivery service offering groceries and other daily necessities, will remain at $299, Amazon said on its website. While current Prime users will continue receiving the service, Amazon said it is e-mailing customers with renewal dates for their membership. http://www.bloomberg.com/news/2014-03-13/amazon-com-raises-prime-price-for-first-time-to-99.html
