Amazon plans to offer drive-up grocery pickup at Whole Foods Market stores for the first time — the latest integration between the companies since the tech giant bought the grocery chain for $13.7 billion last year.

Grocery pickup will debut at Whole Foods stores in Sacramento, Calif., and Virginia Beach, Va., on Wednesday. More cities will follow later this year, the company says.

Amazon currently offers free two-hour delivery from Whole Foods in some U.S. cities through its Prime Now service. The stores in Sacramento and Virginia Beach are among them, and the pickup service is an extension of the same Prime Now system.

Customers using the Prime Now app to order from stores where both pickup and delivery are available will be able to select either.

Amazon Prime members can use the service at no extra charge if they order at least $35 worth of items, with items ready for pickup about an hour after ordering. Alternatively, they can pay $4.99 for pickup in 30 minutes.

Prime Now shoppers will bring orders to cars parked in designated spaces in the Whole Foods lots.

Grocery delivery service Instacart, whose partnership with Whole Foods predates the Amazon acquisition, continues to offer delivery service from Whole Foods stores.

In addition to pickup and delivery, Amazon offers Prime members discounts on some items in Whole Foods stores across the country.

Amazon has been testing the concept of grocery pickup at two Seattle locations since last year, in the Ballard and SoDo neighborhoods, under its AmazonFresh Pickup brand. The Whole Foods grocery pickup service isn’t related.
