Now, you can buy your organic produce and pick up Christmas packages at the same time.

After Amazon purchased Whole Foods Market earlier this year, the e-commerce giant moved swiftly to capitalize on the marriage, including adding Amazon Lockers to multiple stores throughout Southern California.

Amazon Lockers are self-service kiosks where customers can pick up items bought at Amazon at a time and place that’s convenient for them. In some instances, certain returns also are allowed by using the lockers. During the holidays, locker use likely increases as consumers look for secure ways to receive packages without worrying about doorstep theft.

Whole Foods stores in Southern California recently adding Amazon Lockers are in the following cities and communities: Newport Beach (Fashion Island), Huntington Beach, Irvine, Tustin (The District), La Jolla, Long Beach, Glendale, Sherman Oaks, Venice, West Los Angeles, 23rd & Wilshire, Beverly Hills, Brentwood, Del Mar, Hillcrest, Oxnard, Plaza El Segundo, Sherman Oaks West, Tarzana, Torrance, Valencia, Westwood and Woodland Hills.

Whole Foods, founded in 1978, has struggled to differentiate itself as competitors also now offer a plethora of fresh and organic foods. In addition to other natural and organic grocers, it has cited pressure from restaurant chains, meal-delivery companies and traditional supermarkets such as Kroger.
