C2C, or consumer-to-consumer, refers to the process of individuals buying and selling goods or services directly to each other, without the involvement of a middleman or business entity. This type of transaction is typically conducted through online platforms or marketplaces, allowing individuals to connect and exchange products or services with ease. C2C transactions often involve used or secondhand items, but can also include handmade or unique goods. With the rise of e-commerce and social media, C2C has become a popular and convenient way for individuals to engage in commerce and connect with others in a global marketplace.
