BANGOR, Maine — As of last weekend, Bangor is down to one Staples location.

The Union Street Staples at the Airport Mall closed its doors Saturday, according to a manager at the other Staples location near the Bangor Mall. The manager did not know how many employees had worked at the shuttered location.

After a disappointing fourth quarter performance, Staples announced in early March that about 225 stores across the country would close by 2015 in hopes of cutting costs by $500 million.

The office and technology supplies franchise has more than 2,000 stores worldwide.

The Union Street store was one of a dozen in Maine. One of Augusta’s two Staples — the one on Marketplace Drive — closed in 2011, according to the Kennebec Journal.

“With nearly half of our sales generated online today, we’re meeting the changing needs of business customers and taking aggressive action to reduce costs and improve efficiency,” Staples’ chief executive Ron Sargent said in a statement announcing the planned cutbacks.

Staples said it would be shifting more of its focus to online sales.

Staples officials did not immediately return calls requesting comment. It’s unclear when the store was notified it would be shutting down.

The manager who answered the phone at Bangor’s other Staples said there were no immediate plans to close that location.
