Beginning July 27, Hy-Vee will distribute more than 3 million free face masks to those entering its stores in an effort to protect customers and employees, the company said in a statement. The effort is part of an initiative by Hy-Vee called “Mask It Up to Shut COVID Down. It’s Your Choice.” The West Des Moines-based grocer requires employees to wear masks but is not requiring customers to wear masks while shopping.
