Genius technique for winning negotiations

When making a big purchase like a car, avoid being too precise in your bid (like $23,542 versus $23,500). In a recent study in the journal Psychological Science, real estate agents evaluated offers on a listing and jewelers reviewed prices for a diamond necklace. The results: Experts thought overly precise offers suggested overcompensation and lack of bargaining savvy, whereas less precise numbers telegraphed greater competence.
