Amazon adds 1-hour and 3-hour delivery options, but convenience comes at a premium

What just happened? Amazon has launched new 1-hour and 3-hour delivery options in the US. The service is available on more than 90,000 products and arrives as Walmart, among others, continues to make ultrafast delivery a bigger part of its appeal to shoppers.

The new delivery windows are rolling out in major metro areas such as Los Angeles and Chicago, as well as smaller cities including Boise, Idaho.

Amazon says the 3-hour option is now live in more than 2,000 cities and towns across the country, covering everything from everyday essentials and pet supplies to toys, electronics, and toilet paper.

More speed costs extra money, of course. Prime members pay $9.99 for 1-hour delivery and $4.99 for 3-hour delivery, while non-Prime customers are charged a hefty $19.99 and $14.99, respectively.

Eligible products are marked with new "in 1 hour" and "in 3 hours" filters ...
