Amazon's one-hour delivery service is coming to Baltimore and Miami. Prime Now lets Amazon Prime subscribers order from a limited range of products — including toys, books, and toiletries — and select either free two-hour delivery, or one-hour delivery for $7.99. The service, which first appeared in New York last December, is accessible via a dedicated Prime Now app on iOS and Android and is available seven days a week between 8am and 10pm.

"Customers in Manhattan and Brooklyn love Prime Now—it means you can skip a trip to the store and get the items you need delivered right to your door in under an hour," said Dave Clark, Amazon’s senior vice president of worldwide operations in a press release. "Since launching, we’ve seen high demand on everything from essentials like water and paper towels to more surprising deliveries like getting a customer a hard-to-find, top-selling toy in 23 minutes—we are excited to continue delivering to customers in record-breaking time."

The service is rolling out in "select Baltimore and Miami zip codes" from today, with Amazon promising that it'll be expanded to additional areas in both cities "soon."
