Input:  Person1:     Steven , what's your idea of price ?  
 Person2:  The best we can do is $ 120 per case .  
 Person1:      I'm afraid that's impossible . You can't expect us to reduce it to that extent .  
 Person2:  I think you are well informed about the prevailing market.Some Spanish firms are offering the same at much lower prices .  
 Person1:      Price can't be separated from quality . A comparison of the quality of our products with that of rival goods will show you that ours is far superior .  
 Person2:  It's true yours are of better quality . But your price is still on the high side even if we take quality into consideration . How about meeting each other half way ?  
 Person1:      Well , I'll have to think about it and get back to you in about 30 minutes .  
 Person2:  Take your time , please .
