Kasha, amein!
My only answer is the influence of the goyim via what the world calls FEMINISM!
Health, while you didn’t define feminism you definitely implied that feminism is the cause for women routinely going shopping.
Feminism is the mixing up of the yoitzres of what male and female roles are.
Compulsive shopping is the result of an emptiness that the soul feels- a spiritual void that needs to be filled.
Any compulsion is a human’s way of coping with a spritiual void.
