This a absolutely fascinating book. We all have the potential to negotiate, this book unleashes that power.
Most of the time we walk into a store and pay the sticker price. This book teaches everyone that they have the power to negotiate on everything.
Although I did find most of the tactics are more useful for people with more free time (retiree's), the other tactics have been extremely helpful.
And from traveling abroad; Germany, Morocco, Czech Republic, Poland. I can tell these tactics work internationally.
