The present invention relates to a method and system for selling and buying items at auction using information about the purchase of items via an online shopping mall website. In order to sell and buy used items, a used item seller does not need to separately provide pieces of information about used items, and can perform a transaction for the used item using only a minimum number of inputs or actions, thus saving temporal and material costs caused by the disposal of used items. As a result, the present invention can offer convenience to the sellers of used items and can allow the buyers of used items to reasonably fix the states or prices of their desired used items and purchase relevant used items.
