Seven 24-hour New Jersey Walmarts have cut down on their hours, and will now be shut for six hours at midnight, according to a report in the Star Ledger.

“The shopper-less period will allow the stores to reallocate their resources to clean up and stock up in preparation for higher-volume hours,” the report stated. The stores will reopen at 6 a.m.

The change will affect Walmarts in Teterboro, Vineland, Woodbury, Secaucus, Bayonne, Kearny and North Bergen.
