Who was the first city to boycott imported english goods

I think it's Philadelphia but I am not sure  

I'll give this a shot. 
The Houghton Library at Harvard not long ago found eight "subscription sheets" that circulated in Boston in 1767. The sheets were drawn up at a meeting in Faneuil Hall on October 28, 1767, in reaction to the Townshend Acts, which had passed in the British Parliament earlier that year, levying takes on a variety of British goods imported to the colonies. The subscription sheets advised colonialists to boycott the taxed goods in approval of products made in the colonies. 
(It was an early form of the "Made in America" movement.)
