In case you didn't have enough reasons to buy Amazon Prime, here's a new one: Starting Monday, those without Prime will have to pay more to get free shipping.
Amazon has quietly raised the free-shipping requirement, meaning you'll have to add $50 worth of goods to your cart to get free shipping.
Before Monday, you could get free shipping with any purchases totaling at least $35, or any book purchases totaling at least $25.
This could attract new customers to Amazon Prime, the company's $99-a-year service that offers a host of sweet perks, including free two-day shipping on many products and access to Amazon's massive music, movie, and TV libraries.
Amazon Prime is a great deal for customers, but it's even sweeter for Amazon: Data shows that Prime members spend more—and more often—on Amazon.com than nonmembers. That's why Amazon is continually coming up with ways to get people to join Prime. Last month, it announced that Prime members would get 20 percent off any new video games for up to two weeks after their release dates.
