It's imaginable that there's a very short-term deadline affecting a deal. But remember: that puts the side with the deadline at a disadvantage, not an advantage. Consider these examples: really needing to sell something for the money, desperately needing someone to fill a job, needing to use a scarce item in the short term, etc. If one of these is happening for real, then the offer they make will have to be compellingly high and convincing, demonstrating their position of weakness. If someone offered you 5X your normal rate and explained they needed a job done this weekend, that's not a negotiation strategy on their part. But feigning indifference and giving you a short-term deadline for an offer you're unsure you can beat -- that's just a negotiation move, and personally, I would call them on it. Again, I don't want to be responsible for failed application of this :-)
