The robbery was reported just after 8:00 p.m. Sunday at the Rite Aid located in the 1300 block of East Washington Lane.
Police say that a male stayed inside the store after closing and, once the store closed, he produced a gun and ordered the employees to open the door for the other two suspects who were armed.
The workers were handcuffed as the bandits took about $3,000 in cash along with lottery ticks, cigarettes and cigars.
The employees were not hurt.
Police are now reviewing surveillance video from the store in an effort to identify the suspects.
