Walmart division Sam’s Club is now offering same-day grocery delivery through Instacart in certain markets.

The service is available to shoppers in St. Louis, Dallas-Fort Worth and Austin, Texas, according to a news release. Groceries will be delivered from 40 Sam’s Club stores.

“We know our members love our mix of exciting items and appreciate it when we make life a little easier for them,” Sachin Padwal, vice president of omnichannel and in-club product for Sam’s Club, said in the release. “Whether it’s Scan & Go, Club Pickup, and now delivery in as little as an hour, shopping with Sam’s Club is getting easier and more convenient, and we’re just getting started. Instacart is a trusted partner by so many customers, (and) we are thrilled to be launching this service with them.”

The delivery option is expected to become available in more markets throughout the year. Instacart provides delivery for $5.99 per order of $35 or more, while Instacart Express members that pay $149 per year or $14.99 monthly get unlimited same-day delivery from Instacart retailers.

Consumers can order from Sam’s Club without the membership traditionally required to shop the stores, but members will receive lower prices.

With the addition of Sam’s Club to its roster, Instacart is now a partner of the eight largest grocers in North America, according to the company.

Instacart recently closed a Series E fundraising round of $200 million, bringing the total raised since launch to nearly $900 million. The organization is now valued at $4.2 billion, according to the company.
