Compulsive buying disorder

Compulsive buying disorder (CBD) is characterized by an obsession with shopping and buying behavior that causes adverse consequences. It "is experienced as a recurring, compelling and irresistible–compulsive urge, in acquiring goods that lack practical utility and very low cost resulting in excessive, expensive and time-consuming retail activity [that is] typically prompted by negative affectivity" and results in "gross social, personal and/or financial difficulties".
