Abstract: A system, method, and computer program product provides discounted aggregated purchasing. A method for promotional discounted aggregated purchasing may include determining a volume discount matrix for a product to be available during a promotional period, accepting bids from a plurality of consumers indicating a price each consumer is willing to pay for the product, placing a hold on payment cards of the consumers who have entered bids, each hold being for the amount of each bid, at a conclusion of the promotional period, determining a price for the product based on a final discount level that is determined based on the received bids and on the determined volume discount matrix, and performing transactions for the product for all consumers who bid an amount greater than or equal to the determined price.
