“We are regularly testing new product updates, categories and initiatives, in order to provide the best possible experience for our community,” an Airbnb spokesperson said in an email. “As part of that, following the launch of Airbnb Services earlier this year, we will pilot groceries with Instacart in select markets across the U.S. beginning in January.”

The new kitchen stocking service will be available to select hosts with qualifying listings in Phoenix, Orlando, and Los Angeles, according to a help page on Airbnb’s website.

The news was first reported by Bloomberg.

If hosts receive their guests’ preorders and put them away before they check in, they will receive $25, according to the the help page. They will also receive a $100 bonus for their first completed order. Guests will be able to place orders on Instacart from the Airbnb app up to three weeks before their stay.

“By bringing groceries powered by Instacart directly into the Airbnb app, we’re making it easier for guests to stock their kitchens and feel at home from day one,” an Instacart spokesperson said in an email. “We’re excited to partner with Airbnb on this pilot and put our broad retailer network and leading technology to work for their guests.”

The new partnership with Instacart marks the latest addition to Airbnb’s “Services,” which launched in May and allow guests to book services and experiences, like getting a massage, haircut, or chef-prepared meal. While these offerings can be added to your stay, they can also be booked independently.

The launch of Services put Airbnb more directly in competition with other travel companies such as Tripadvisor, Booking.com, Viator, and GetYourGuide.

Airbnb CEO Brian Chesky has said Services will help the company add $1 billion or more in revenue a year.
