Mayor Rob Greenbaum posted on his Facebook page that the Mount Olive store had closed, while the Hackettstown Patch reported and Townsquare Media New Jersey News confirmed that the Linden store had also closed Thursday.

In his post, Greenbaum said he was told the closure was "a business decision of the company. The mayor also noted that the store's pharmacy will stay open through Jan. 27.

The closures are happening all over the country. Syracuse.com reported that several stores in upstate New York and other locations were closing. Other closures, according to the report, are happening in Indiana, Tennessee, Texas, Georgia, Ohio, and Louisiana.

Business Insider reported that a total of 63 Sam's Club locations will be closing across the country, affecting thousands of employees. A Twitter message by the company said that the closures were done after a "thorough review of our existing portfolio," in order to "better align our locations with our strategy."
