1st of its kind to work?
Let's for example take france, and Americas boycott of french wines.
If you listen to french winemakers bemoaning the rapid loss of American sales of high end french wines you may change your thoughts.
Until a year ago I had a service company that serviced grocery stores and I would talk to wine representatives and discuss whether they thought there was a decline in french wine consumption by their customers and they were emphatic, YES.
Let me rephrase,...boycott of something in America made by Americans.
