A purchase made from one individual to another on an online auction site like eBay is categorized as a consumer-to-consumer (C2C) transaction. This classification occurs because the transaction involves two consumers—individuals who are not businesses—engaging directly with each other in the marketplace.

C2C transactions are typically facilitated by a third-party platform, which in this case is eBay. The platform provides the necessary infrastructure for buyers and sellers to interact, list items for sale, and complete transactions. This type of transaction is distinct from other forms like business-to-business (B2B), which involves commerce between two businesses, or business-to-consumer (B2C), which involves a business selling to a consumer. A2A, or agent-to-agent, typically refers to transactions between agents and is not applicable in this scenario.

Therefore, C2C accurately describes the online auction setting where individuals buy and sell goods or services among themselves.
