Input: Consider Input: Person1: Even with volume sales our costs for the Exec User won't go down much .
Person2: Just what are you proposing ?
Person1: We could take a cut on the price . But 25 % would reduce much our profit margin . We suggest a compromise 10 % .
Person2: That's a big change from 25 % ! 10 % is beyond my negotiating limit . Any other ideas ?
Person1: I don't think I can change it right now . Why don't we talk again tomorrow ?
Person2: Sure . I have to talk to my office anyway . I hope we can find some common ground on this .
Person1: Robert , I have been instructed to reject the numbers you proposed , but we can try to come up with something else .
Person2: I hope so , Dana . My instructions are to negotiate hard on this deal , but I'm trying very hard to reach some middle ground .
Person1: I understand . We propose a structured deal . For the first six months , we get a discount of 20 % and the next six months we get 15 % .
Person2: Dana . I can't bring those numbers back to my office , they'll turn it down flat .
Person1: Then you'll have to think of something better , Robert .
