Don't have time to stop by Walmart for groceries? No sweat. Soon, Uber and Lyft will be able to handle it for you.

Walmart will soon begin piloting a new grocery delivery service through Uber, Lyft, and Deliv. The service is slated to launch within the next two weeks in Denver and another undisclosed city.

Here's how it will work: place your grocery order online and select a delivery window. Walmart's personal shoppers will prepare your order, and request a driver from one of the services to pick it up and bring it to you. Walmart will notify you when the driver is on their way, and you can check "get groceries" off your to-do list.

"It's all seamless to the customer," Walmart said.

You will, of course, have to pay for this convenience. Walmart is charging a $7 to $10 delivery fee; you won't have to pay the driver any extra, though.

Walmart has been quietly testing this idea at Sam's Club in Miami since March. The process there is similar: the store's personal shoppers prepare orders, and they're delivered via Deliv.

"We're thrilled about the possibility of delivering new convenient options to our customers, and about working with some transformative companies in this test," Walmart wrote in a blog post. "We'll start small and let our customers guide us."

Meanwhile, Walmart may in the future add another convenient option: drone deliveries. Following the lead of Amazon and Google, the retailer last year asked the Federal Aviation Administration for permission to test drones for things like package delivery and inventory monitoring.
