Purchaser-driven keyword-based transaction system for transacting product at low price

Abstract

A purchaser-driven system for transacting a product at a low price is provided. The purchaser-driven system includes an operating server, a keyword transaction server, a purchaser terminal and a seller terminal. The purchaser selectively performs an immediate purchase or a joint purchase at a price lower than the showrooming price, and particularly the commission or the advertisement commission is adjusted through the purchaser evaluation and the target advertisement performed by grouping the remaining sellers filtered when the specific seller is selected, and correspondingly discounted amount is fed back to the purchaser, so that both the purchaser and seller receive benefits.

Dependencies are inferred from the claim text.
