Amazon continues to be aggressive in the grocery industry, announcing on Wednesday a curbside delivery service that will allow Prime members to order groceries from select Whole Foods locations and pick them up at the store within 30 minutes without leaving the car.

The e-commerce giant is allowing its Prime subscribers to order food from the Prime App or and select a delivery time. Customers can then drive to their selected Whole Foods location and wait in the parking lot where someone will drop off their goods.

"Pickup from Whole Foods Market is a perfect option for customers who want to grab healthy and organic groceries at their convenience, all without leaving their car," Stephenie Landry, worldwide vice president of Prime Now, AmazonFresh and Amazon Restaurants, said in a statement.

"A customer can order at 5:00 p.m., pick up at 5:30 p.m., and we’ll have their groceries loaded into their car just minutes after arrival. For an even faster experience, customers can tell us they are on their way using the Prime Now app and groceries will be ready as they arrive."

Customers can get free pick up for orders that are $35, or they can opt to grab their groceries within 30 minutes for $4.99, the company said. For now, the service is limited to just Sacramento, California, and Virginia Beach, Virginia, but more cities are expected to be added in 2018.

Amazon has been cutting prices and offering more delivery perks since acquiring Whole Foods for $13.7 billion in June 2017. Customers with a $119 Prime membership can also receive discounts on Whole Foods products and free expedited delivery.

Amazon has over 100 million subscribers to its Prime service, which offers discounted shipping rates and access to music and movie streaming.

On July 18, the company reached a record-breaking market capitalization of $900 billion after its Prime day shopping event -- a 36-hour promotion that helped it sell more than 100 million products worldwide.

Shares of Amazon (AMZN) increased roughly 1 percent to $1,881.17 in early trading Wednesday.
