The invention relates to a promotion 
payment time limit donation 
system. The method is characterized by comprising the following steps: a 
server where the promotion 
system is located creates promotionaccording to the input 
signal; and the promotion 
system activates promotion according to the input 
signal, generates a promotion order 
pool for order interception and 
order entry into the promotion system when there is limited donation in the promotion action of promotion, and matches promotion according to whether the 
payment time of the order is within the start-end 
time range of promotion. Themethod has the advantages that the disordered orders can be accurately added according to the 
payment time sequence in a limited manner, and wrong delivery is avoided; all the orders do not need to be intercepted, only the orders meeting the promotion order 
pool need to be intercepted, other orders can be normally downloaded from the 
storage management system for delivery, the number of the intercepted orders is greatly reduced, and the order delivery 
time efficiency is greatly improved; the limited donation system is automatically operated by a computer, and manual intervention is not needed; however, the interception time can be manually modified, and adjustment can be flexibly carried out according to conditions.
