OREANDA-NEWS. February 24, 2016.  Customers will now have to buy at least \\$49 worth of goods, up from \\$35, to qualify for free shipping. For those making book purchases, the freebie kicks in at \\$25.

A new Help page posted by Amazon explains the new free-shipping process. With free shipping, orders are delivered within five to eight business days.

The jump in the minimum amount for shipping applies only to shoppers who don't subscribe to Amazon's Prime service. Amazon last upped the minimum price for free shipping in 2013 from \\$25 to \\$35.

Amazon Prime, which offers free two-day shipping, has helped the company grow faster than the broader e-commerce market, but it's also added to shipping costs and fulfillment costs, whose growth has been outpacing that of revenue. Amazon remains a top online retailer but still must contend with competition from brick-and-mortar stores such as Walmart, Target, Best Buy, Costco and Sam's Club.
