Prime Now customers can now get two-hour home delivery through Alexa, the company said Tuesday.
The digital assistant which powers Amazon Echo has offered voice shopping for a while, but delivery options have until now been limited.
The service will initially offer "the full Prime Now catalog with Alexa, including tens of thousands of items," said Assaf Ronen, Amazon's vice president of Voice Shopping.
By bringing the service to Alexa voice shopping, the company is trying to further carve out its niche as the shopping technology of choice, as products like Google Assistant challenge Amazon's position in the digital assistant space.
Correction - An earlier version of this story misstated which products are available for two-hour delivery.
