Customers and employees across the country were surprised to find their local Sam’s Club closed on Thursday. Upon approaching the doors of several locations, people found notices saying their store was shut down. Some notices announced that the closure would be permanent beginning on January 26 or 28, while others said the store would reopen at a later time.

The series of closures appear to be coupled with varying degrees of miscommunication. Employees at some locations had no knowledge of their store's closing until they couldn't get inside. Others were told through a letter earlier that same day. Meanwhile, a WalMart official told Business Insider that the $45 membership fee will be reimbursed to customers impacted. 

The closures follow the news that WalMart will be increasing its minimum wage for employees to $11 and offering up to $1000 bonuses. WalMart owns the Sam’s Club chain, and some speculate that the closures are a result of the aforementioned changes.

Closures have so far been reported in Indiana, New York, Florida, Connecticut, and elsewhere for a total of 63 stores. Business Insider predicts that more than 11,000 employees could be impacted. “After a thorough review of our existing portfolio, we’ve decided to close a series of clubs and better align our locations with our strategy,” the chain tweeted.
