Input:  Person1:     If I remember correctly , time of delivery is another point in which we differ .  
 Person2:  That's right . Let's go into details of it .  
 Person1:      Ok . I hope you can have these goods delivered before the end of September . We'd like them to be ready in time for our Christmas sales .  
 Person2:  Christmas doesn't come until the end of the year , does it ?  
 Person1:      No . But in the United States , the Christmas season begins about a month before December 25 .  
 Person2:  Well , I'm afraid a little bit difficult for us to advanced the time of shipment . Our manufacturers are fully committed at the moment .  
 Person1:      I hope you can try to get them to step up production .  
 Person2:  They are already working three shifts a day to step up production as new orders keep pouring in .  
 Person1:      If that's the case , there's nothing to be done about it .  
 Person2:  I'm sorry .  
 Person1:      What's your last word as to the delivery date then ?  
 Person2:  By the middle of October . This is the best we can do .  
 Person1:      All right . I'll take your words at that .  
 Person2:  Good . Let's call it a deal . And we'll do our best to advance the shipment , but your letter of credit should be opened early September .  
 Person1:      I promise .
