A shopaholic is a person who has an uncontrollable urge to shop, often spending more money than they can afford. A compulsive shopper is someone who is unable to resist the temptation to buy things, even when it is not necessary or practical. They may be driven by emotional needs, such as a need for comfort or a need to feel in control. Compulsive shopping can lead to financial problems and can have a negative impact on relationships.
