Amazon is testing an Uber-like service for delivering its one-hour Prime Now packages that will enlist people to deliver packages for Amazon with their own cars. In order to offer the speedy deliveries Amazon will pay drivers $18 to $25 an hour via its new Amazon Flex program. Drivers have to be at least 21 years old and pass a criminal background check and motor vehicle records review. The service delivers a wide range of items including paper towels, wine and beer , chilled and frozen items like milk and ice cream and televisions and Kindle device in one or two hours. On its website, Amazon said currently it's only offering the program to drivers, but in the future it might let people bike or walk the packages to their destination.
