Amazon says it has a way to start shipping something even before a customer order is placed.
The online retail giant says what it calls "anticipatory shipping" involves using everything the company knows about a customer's shopping patterns to box and ship items that customers in a specific area will likely want.
That includes data on previous orders, product searches and online shopping cart contents.
Amazon thinks cutting delivery times can lead to more orders and satisfied customers.
It hasn't said whether the new system has already been implemented.
