After recently teasing that free one-day Prime shipping was coming, Amazon today confirmed that the feature is now available widely.

Prime Free One Day shipping is now available on more than 10 million products sold by Amazon. The service began rolling out in early April, and Amazon says that it will continue to expand the selection and delivery areas for free one-day shipping with Prime.

"We’ve strategically grown our network in the U.S. to include 110 fulfillment centers, 40 package sortation centers, 100 delivery stations, and 20 air gateways all to be closer to our customers," Amazon explains.

Amazon Prime also offers free same-day delivery on more than three million items on qualifying orders over $35. If you order an eligible product in the morning, Amazon says it'll get it to you that same day before 9:00 pm. Same-day delivery is also available for products under $35, but it costs Prime members $5.99 per item.
