They were captured on surveillance video Monday night walking into the 7-11 in the 1800 block of Stenton Avenue in the city's Ogontz section.
Both men used guns to threaten an employee. They then ran east on Stenton Avenue with only ten dollars and several packs of cigarettes.
Then on Wednesday police believe the same two men struck again. This time the suspect entered the Ogontz Market located at 7153 Ogontz Avenue, pulled out their handguns and demanded money. The employees handed over $550 in cash and fourteen money orders valued at $620.
The suspected then fled in a silver Chrysler north on Forrest Avenue.
