Amazon will now deliver groceries to select Los Angeles neighborhoods in an expansion of its AmazonFresh service. Only available "in select zip codes as a free 90-day trial to Amazon Prime members," AmazonFresh lets you order food items and get them delivered on the same day. As part of the launch, Amazon has also created an LA spotlight, highlighting some of the stores that are participating in the service.

Amazon has been toying with the concept of grocery deliveries in Seattle for many years, slowly expanding an initial 2007 pilot to cover a large portion of its hometown. It's not clear if the business is making money yet, but Jeff Bezos told investors last month that the economics of AmazonFresh are moving in the right direction.

The expansion was rumored last week, with Reuters reporting that the LA delivery service could launch within days. Amazon refused to comment on the rumor, but it appears Reuters' anonymous sources were accurate. The news organization also reported that Amazon is planning to launch AmazonFresh in the San Francisco Bay Area later this year, with a further expansion scheduled for 2014.
