Ready to buy? Here’s the exact moment when you should make your offer

Negotiating a deal is part art, part science.

The science part you probably already know. In the last few weeks, I’ve reviewed the best time to book an airline ticket or buy a car, a house, and a computer, among other things.

But one big question still looms: At what point during the actual negotiation do you pull the trigger? Do it too early and you could overpay. Do it too late and you might miss your opportunity altogether.
