One of the factors that can affect a person's consumption behavior is peer group. The individual peers feel a similarity one to another, such as age, needs and goals to strengthen the group. Peer as a group is more influence in choosing how to clothe, hobby, association and other social activities. Teenager is often faced with the acceptance or rejection of peers in the association.
