Men still shop, but men and women differ greatly in their styles of shopping. Women are more conscientious than men. As an example observe a lady buying vegetables. She typically looks over each item carefully before choosing, while a man usually gives it a quick once over before adding it to the shopping cart. Another example is that pile of catalogs that you receive on a daily basis in your mailbox.
Women demand more of a shopping environment.
Men do not browse as a rule. They get what they want and leave. Those trips to the mall are a social event to a woman. That is why it is not uncommon for her to take a friend with her. Most men would not consider rounding up a few friends to browse the local department store.
