Couponing is the practice of using coupons to save money on purchases. Coupons can be found in newspapers, online, or through store apps, and they offer discounts on specific products or services. Shoppers can redeem these coupons at checkout to lower their total bill, making it a popular way to save money on groceries and other items. Many people enjoy couponing as a hobby, often spending time organizing and planning their shopping trips to maximize savings. Some even participate in extreme couponing, where they combine multiple coupons and sales to get items for free or at a significantly reduced price.
