Bulk buying is the practice of purchasing large quantities of products at once, often at a discounted price. This method is commonly used for items like groceries, household supplies, and personal care products. By buying in bulk, consumers can save money and reduce the frequency of shopping trips. Many retailers, such as warehouse clubs and discount stores, offer bulk buying options. This approach can be beneficial for families or individuals who use certain products regularly. However, it is important to consider storage space and the potential for items to expire before they are used.
