Walmart has closed 24-hour pharmacy outlets across the country in an effort to focus on its online and on-site stores.

The closures follow a similar effort by Target, the largest U.S. retailer, to close 24-hrs a day.

Walmart said it closed its pharmacy in Seattle and at the time said it would reopen the stores on a week-to-week basis.

The chain has struggled to attract patients and is looking to expand its on-premises pharmacy network, including opening a second store in California in the coming weeks.

Walmart also said it is working with pharmacies to add more medication to its pharmacy shelves.

Wal-Mart’s move comes amid a broader shake-up at the company as it seeks to diversify its pharmacy business and increase revenue.

WalMart announced in April that it would open a second, on-demand pharmacy at the Seattle store.

The Seattle store will open in December and will offer 24-hours-a-day access to prescription medication.

It is not clear whether the Seattle pharmacy will offer a 24-hr access option.

The company’s other 24-Hrs stores are in Colorado, California, Florida, Georgia, Idaho, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Montana, Nebraska, Nevada, New Hampshire, New Jersey, New Mexico, New York, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Carolina, South Dakota, Tennessee, Texas, Utah, Vermont, Virginia, Washington, Wisconsin, and Wyoming.
