Every savvy shopper knows that coupons can save serious money—but sometimes, they do more harm than good. There’s one common coupon mistake that leads to frustration for everyone: empty shelves before most customers even have a chance to grab the deal. While it might seem smart to stock up when you can, overusing or misusing coupons can unintentionally cause shortages, limit promotions, and even lead stores to change their coupon policies altogether. Understanding this couponing mistake helps you shop smarter, save responsibly, and keep the deals fair for everyone who loves a bargain.
