Consumer-to-Consumer Sales, often abbreviated as C2C, refer to transactions where individuals sell goods or services directly to other individuals. This type of selling typically occurs through online platforms like eBay, Etsy, or Facebook Marketplace, allowing people to reach a wider audience without the need for a traditional retail store. In C2C sales, sellers can list items they no longer need, such as clothing, electronics, or handmade crafts, while buyers can find unique products at competitive prices. This model fosters a sense of community and encourages recycling, as people can buy and sell second-hand items, promoting sustainability in the marketplace.
