E-Commerce sites have introduced new business models for effective and efficient commerce. If we introduce software agent technologies into e-commerce systems, we can further enhance the intelligence of user support. In this paper, we propose a new cooperation mechanism among seller agents based on exchanging their goods in E-GarageSale, our P2P-based distributed electronic marketplace. In E-GarageSale, buyer agents can purchase multiple goods based on discount prices. However, there is a case that seller agent does not have enough goods for trading with several buyer agents at a time. Therefore, seller agents cooperatively negotiate by using an exchanging mechanism for selling goods effectively. By using our mechanism, all seller and buyer agents can increase their utility. Our experiments show that an exchanging mechanism enables seller agents to sell goods in stock effectively.
