Starting today (March 17), Amazon is rolling out one- and three-hour deliveries in certain regions and cities across the U.S.
The three-hour delivery is more widely available in 2,000 cities, according to Amazon. One hour is only available in a few hundred areas within that list.
“Our customers are busier than ever and are looking for new ways to save time while keeping their households running," Senior VP of Worldwide Operations Udit Madan said in a press release. "We saw an opportunity to use our unique operational expertise and delivery network to help make customers’ lives a little easier while unlocking even more value for Prime members."
More than 90,000 products are eligible for the new delivery windows including pantry items, over-the-counter medications, toys and electronics.
There are fees for using the 1-hour and 3-hour delivery options. Prime members will pay $9.99 for a one-hour delivery and $4.99 for three-hour deliveries. If you don't have Prime then the fees go up by $10; $19.99 for 1-hour and $14.99 for three-hour.
How to tell if its available in your area

In its statement, Amazon specified that 1-hour delivery is available in parts of several major metropolitan areas including Los Angeles, Chicago, Oklahoma City, Nashville, Houston, and Washington, D.C., and smaller cities such as Des Moines, Iowa; Boise, Idaho; and American Fork, Utah.
Three-hour delivery is available in over 2,000 cities and towns.

The company set up a new 'getitfast' storefront where you can see if your area gets the deliveries.
As an example, I live in Los Angeles, but apparently, my area isn't eligible for 1-hour deliveries. You can see what's available in the upper taskbar underneath the Rufus AI button.
If you have the option you can filter eligible products by 1-hour or 3-hour availability. You can also use the search bar with new "in 1 hour" or "in 3 hours" search filters.
If you live in an eligible area, the new delivery windows are available now. However, it's not clear if and when Amazon will expand one-hour and three-hour deliveries to other areas.
