Amazon has launched a new 1-hour and 3-hour delivery option for some items, offering customers in over 2,000 cities. The service is available for household essentials such as paper products, personal care items, and over-the-counter medications. Prime members will pay $9.99 for 1 hour delivery and $4.99 if it is available in three hours. The new service does not have a minimum spending limit, but adds a significant fee. However, the service may not be worth the extra cost, with some potentially saving the lives of an emergency item or a last-minute gift.
