Two hours later, police say the same two men entered a Dunkin' Donuts on White Horse Pike through the drive-thru window.
They did the same thing at a store on Erial-Clementon Road in Pine Hill shortly after 3:00 a.m.
Police aren't saying how much cash they stole.
Anyone who recognizes the duo is asked to contact Gloucester Township police at 856-228-4500.
