Extreme couponers are individuals who use coupons to save significant amounts of money on their grocery and household purchases. They often spend hours researching, organizing, and planning their shopping trips to maximize their savings. By combining store sales, manufacturer coupons, and loyalty programs, they can sometimes get items for free or at a fraction of the original price. These shoppers typically have a deep understanding of store policies and couponing strategies. They may also participate in online communities or forums to share tips and tricks. Extreme couponing can lead to stockpiling, where they accumulate large quantities of products, ensuring they have enough supplies for their needs.
