PURPOSE: A concurrent purchase method in an online shopping mall is provided to collectively process a payment and a commodity delivery in each shopping mall, and to enable a delivery company to discount a delivery cost for the same kind of commodity according to the ordered number. CONSTITUTION: The method comprises several steps. A commodity purchase request signal is received, personal data on a purchaser is checked, prior discount coupon data is checked, and a message including an effective period of the coupon and data on a delivery company is transmitted to the purchaser(S111-S114). An ordered commodity is searched in a database, the same commodity as the commodity delivered by the delivery company is extracted, a discount amount is calculated on a basis of the purchase number and the delivery cost, and the calculated discount amount is transmitted to the purchaser(S115, S116). If the commodity purchase determination signal is received, a purchase acceptance number is offered to the purchaser(S118-S120). Prior discount coupon data is searched in a database(S121). If there exists prior discount coupon data, the delivery company and an effective period included in the discount coupon data are checked(S122). If the effective period is normal, the discount amount is applied to a current purchase specification and the result is stored at a purchase management database and a discount management database(S123).
