A hybrid single and aggregation sale system is disclosed. This invention provides the mechanism: aggregating the individual purchase, grouping into the buying power, promoting efficient way for selling goods. The system has two styles: explicit and implicit style. Explicit style defines the limitation of availability etc. deal start time, end time, which the implicit style doesn't define. For explicit style, despite the time of purchasing, the system counts the total sold units in each sequential aggregation period from start time to end time, applies the maximum sold units as buyer's aggregation sold number, and thus the same final aggregation price will apply to the buyers who entitles same aggregation period. For implicit style aggregates the total units depending on the individual entitled aggregation period, the different order time might results the difference on the final aggregation price. The system allows the price match for disadvantaged buyer, etc earliest buyer. The buyer pays the price at front; the sellers handle and ship the items after the confirmation. After system aggregate the sale, the system credits the difference between prepaid and final aggregating price into the customer's prefer account. Buyer should order with caution because the buyer is bound to the deal.
