Consumer-to-Consumer (C2C) ecommerce is a type of electronic commerce that involves transactions between individual consumers. C2C ecommerce platforms facilitate the buying and selling of products and services between consumers, without the involvement of businesses. Here are some key features of C2C ecommerce:

1. Online Marketplaces: C2C ecommerce is primarily conducted through online marketplaces, such as eBay, Craigslist, and Etsy. These platforms allow consumers to create listings for products they want to sell, and browse listings of products they want to buy.
2. Peer-to-Peer Transactions: C2C ecommerce platforms typically facilitate peer-to-peer transactions, in which the buyer and seller communicate and negotiate directly with each other. This allows for more personalized transactions and often leads to lower prices for both buyers and sellers.
3. Reputation and Feedback Systems: C2C ecommerce platforms often have reputation and feedback systems, which allow buyers and sellers to rate and review each other. This helps to build trust between buyers and sellers and ensures that transactions are fair and secure.
4. Secure Payment Systems: C2C ecommerce platforms typically offer secure payment systems, which protect both buyers and sellers from fraud and ensure that payments are made securely and promptly.
5. Local Commerce: C2C ecommerce often includes local commerce, in which buyers and sellers are located in the same geographic area. This can lead to more efficient and convenient transactions, as buyers can often pick up items in person and sellers can avoid shipping costs.

C2C ecommerce offers several benefits to consumers, including the ability to sell unwanted items and make extra money, access to a wider range of products and services, and the ability to find unique and hard-to-find items. However, C2C ecommerce also poses challenges, such as the need to navigate complex and often unregulated marketplaces, the risk of fraud and scams, and the need to manage shipping and logistics for online transactions.
