The incident happened at 5:10 p.m. on Wednesday, June 19th at the Weavers Way Co-Op at 8424 Germantown Avenue.
Police say two men entered the store and appear to target the woman.
One of the suspects bumps into her, and uses a blue and white garment bag to conceal the theft.

The suspects left through the rear door and fled in an unknown direction.
