Nibbles = get the other party to feel like this is a done deal, then push them for further small concessions. (nibbles are one-way) example: "gee, that job offer sounds great!! but there is one thing- just caught that I have to pay for parking. Can you do anything there to make up for that?" Expanding the pie = find a compromise that benefits both parties: "I understand you're extremely short on office space until the new office space is built out, and your office will be a painfully long commute for me until my lease runs out and I can move closer to the office. How about I work from home for a while?"
