Amazon on Thursday announced that it's expanding its one-hour delivery "Prime Now" option beyond the streets of Manhattan and Brooklyn. Beginning Thursday, Amazon Prime customers can now expect to see that 60-minute delivery window as an option in Miami and Baltimore.

Amazon said one-hour deliveries in Baltimore and Miami are only offered in "select' zip codes and that it will expand the offering to additional zip codes in those markets soon. The service is available as an option between 8:00 a.m. and 10:00 p.m. seven days a week, Amazon said, and will cost you $7.99 on top of whatever you're ordering. If you can spare another hour, you can also opt for free two-hour delivery.

The firm promised that "new cities" will start to offer Prime Now throughout 2015. Hit the source to find out if it's available in your area.
