PURPOSE: A group purchase service providing device and a user leading group purchase method using the same are provided to enable a user to post and promote the desired product, thereby enabling the user to receive discount benefits through group purchase. CONSTITUTION: A product information searching unit(110) searches whether product information which is the same or similar with product information posting a site for group purchase is posted based on a keyword and information related to the keyword inputted by a user terminal. A product information posting unit(120) receives at least one product information from the user terminal. A data transmitting/receiving unit(140) performs data transmission and reception. When a transaction information renewing unit receives a renewed contract condition about transaction information as a responding data, the transaction information renewing unit(150) renews the transaction information based on the responding data. A transaction information storing unit(160) stores an history about group purchase transaction information. When a transaction contract contracting unit(170) receives transaction contract approval data about the transaction information as the responding data, the transaction contract contracting unit executes a group purchase transaction process about the corresponding product based on the transaction information. When the group purchase transaction contract is contracted, a purchase process progressing unit(180) progresses a purchase process for group purchase about the corresponding product.
