It happened Thursday along Ridge Avenue.
Surveillance video shows a man wearing a safety vest entering the store.
Behaving like a shopper, the man makes a phone call.
Minutes later, a second suspect enters the store. He shows a gun and jumps over the counter, demanding money.
The man in the vest then also pulls out a gun.
The two got away with $200 in cash, plus boxes of cigarettes.
The 7-Eleven clerk on duty at the time was not hurt.
Anyone who recognizes either suspect or has other information about the case is asked to contact Philadelphia police.
