The San Francisco based grocery chain Instacart is making moves to expand into Southern California.

The company already services almost 2 million households in the Los Angeles area and more than 49 million nationwide; the expansion would add an extra million to their California total.

The company would allow users to shop online at Stater Bros., Smart & Final, Costco, Petco and Whole Foods Market and Ralphs and have their groceries delivered to their doorsteps in as little as an hour.

Regional director of Instacart’s operations west of the Mississippi Sean Twersky says the company plans to hire over 300 shoppers to handle the extra business.

“We’re actually doing a lot of launches concurrently. We just did Tulsa last week and we’re launching in new areas all the time.”

The Southern California expansion will bring Instacart into 14 LA County cities, including: Pomona, Baldwin Park, Covina, West Covina, Diamond Bar and Claremont and others.

The expansion into San Bernardino County will include almost 20 cities, including: Chino Hills, Rancho Cucamonga, Ontario, Montclair, Upland, San Bernardino and Fontana.

The Riverside County expansion will add 24 communities, including: Riverside, Indio, Coachella, La Quinta, Palm Desert, Palm Springs and Corona.

In Ventura County, service will be available in Ventura, Casitas Springs, Mussel Shoals, Dulah, Faria, Camarillo, Oxnard, Port Hueneme and Saticoy.
