Impulse buying is when a person makes an unplanned purchase, often driven by emotions rather than necessity. This can happen when someone sees a sale sign or a new gadget that catches their eye, leading them to buy something they didn't intend to. These spontaneous decisions can be influenced by factors like mood, advertising, or even the layout of a store. Many people experience impulse buying, especially during events like Black Friday or holiday shopping. While it can be fun to treat oneself occasionally, frequent impulse purchases can lead to financial stress. It's important to be mindful and consider whether a purchase is truly needed before making a decision.
