Amazon continues to expand its Prime Now one-hour deliveries. The online retailer has announced that the service is now available in San Jose, San Francisco and other places around the Bay Area, including Mountain View and Cupertino -- Google and Apple's home, respectively. Prime Now's also hitting San Antonio, which joins Austin, Dallas and, most recently, Houston as the Texan cities where Amazon's ultra-fast delivery offering is live. In case you're not familiar with Now, it lets Prime members receive select orders in less than 60 minutes for a $7.99 fee, with an app that's available for iOS, Android and Kindle devices. Or, if you're not in a rush to get the items, they can be at your doorstep in about two hours free of charge.
