Amazon makes a day shipping standard for Prime members.
The change will only take place in the North American market, Olsavsky listed, but is designed to expand globally, across all countries that offer Prime membership. Amazon said last year that it has over 100 million Prime members worldwide.
Olsavsky said the company would use "all available promises" for free one-day shipping, including existing partners such as the US postal service and UPS as Amazon's own third-party delivery network. But he refused to give specific details, such as the timeline of the rollout, and says that the move involves many different moving parts.
"We take a significant step," he said.
