It happened at 8:00 p.m. Monday outside the Macy's store at the Willow Grove Park Mall.
Abington Police say the victim was entering the second floor parking lot when the suspect walked up behind her, knocked her to the ground, pulled the pocketbook from her shoulder and fled.
Moments after the robbery, police say, surveillance cameras at the Wawa store on Moreland Road caught the suspect using one of the victim's credit cards.
He was wearing a dark colored hooded sweatshirt.
Cameras also recorded the car he arrived in. Investigators say he was a passenger in a maroon late 90s to early 2000s 4-door sedan.
