 Person1:      If I remember correctly , time of delivery is another point on wich we differ .  
 Person2:  That's right . Let's go into the details .  
 Person1:       Ok . I hope you can have these goods delivered before the end of Sep . We'd like them to be there in time for our Christmas sales .  
 Person2:  Christmas doesn't come until almost the end of the year , right ?  
 Person1:       But in the United States the Christmas season begins about a month before Dec . 25 .  
 Person2:  Well . I am afraid it will be difficult for us to advance the time of shipment . Our manufacturers are fully committed at the moment .  
 Person1:       I hope you'll try to get them to step up production .  
 Person2:  As new orders keep pouring in , the workers are working three shifts to step up production .  
 Person1:       If that's the case , there is nothing more to be said .  
 Person2:  I am sorry .  
 Person1:       What's your last word as to the date then ?  
 Person2:  I said by the middle of Oct . This is the best we can promise .  
 Person1:       All right . I'll take you at your word .  
 Person2:  Good . Let's call it a deal . We will do our best to advance the shipment , but your L / C should be opened early Sep .  
 Person1:       I promise .
