Walmart is headquartered in Arkansas. Customers who live in another state who go to
www.walmart.com can choose to buy from the website and have the headquarter Walmart in Arkansas fulfill the order without having any local license.
If Walmart chooses to deliver a portion of the product or service in another state where local licensing is required, then Walmart can either sub-contract the delivery of those services to another licensed business, or Walmart can apply for a corporate branch license in the state to open a branch location.
