Amazon today announced that Prime Now, it’s one-hour delivery service, is now available to select zipcodes in Miami and Baltimore. The service allows members of Amazon Prime the option to pay $7.99 for one-hour delivery, or select two-hour delivery of their Amazon order at no additional charge. When the service launched in December, it was initially only available to Manhattan residents, but quickly expanded to other parts of New York. Today’s expansion to Baltimore and Miami marks the first time the service has been made available outside of New York. You can see if your ZIP code falls within Prime Now’s coverage, and sign up to be notified when it’s available in your area on Amazon’s Prime Now homepage.
