A website enables a motion reverse auction between suppliers of common consumer goods and consumers (buyers). A buyer requests to buy consumer goods/commoditities and indicates the highest price he/she may accept and a minimum quantity he/she intents to buy. Then, during a waiting period, other buyers request to buy the same kind of goods with a price equal or lower than the price indicated by the first buyer. During the waiting period the total requested quantity increases while the accepted prices decrease. Suppliers then bid during a bidding period. The final winner of the auction is the supplier with the lowest selling price and having a quantity of goods equal or bigger to the total quantity requested by the buyers.
