Oniomania AKA Shopalism

Similar to other compulsive behaviors, sufferers often experience the highs and lows associated with addiction. Victims often experience moods of satisfaction when they are in the process of purchasing which seems to give their life meaning while letting them forget about their sorrows. Once leaving the environment where the purchasing occurred, the feeling of a personal reward has already gone. To compensate, the addicted person goes shopping again. Eventually a feeling of suppression will overcome the person.
