Heads up Costco members. You will be required to wear a mask while shopping at Costco starting on May 4, 2020. 

Costco Issued a press release:

Face Mask Requirements

To protect our members and employees, effective May 4th, all Costco members and guests must wear a mask or face covering that covers the mouth and nose at all times while at Costco. This requirement does not apply to children under the age of 2 or to individuals who are unable to wear a mask or face covering due to a medical condition.

The use of a mask or face covering should not be seen as a substitute for social distancing. Please continue to observe rules regarding appropriate distancing while on Costco premises. Thank you for your understanding and cooperation.

Have you been wearing a mask already, or will this be something you have to adjust to? The warehouse giant previously made COVID-19-related restrictions when they limited two customers per membership to combat the virus.
