Negotiating over price is a common practice known as haggling. Haggling is the process of bargaining or negotiating with a seller to get a lower price on an item. It involves both parties making offers and counteroffers until they reach an agreement. This process can be used in many different situations, such as buying a car or house, or even when purchasing everyday items like groceries. Haggling is a skill that requires patience and negotiation skills, but it can often result in significant savings.
