I used to live in Boston and would smoke mainly their blends, especially liked the Thanksgiving Day Blend every year when it was released. But, the way they treat customers is astonishing. I have never seen meaner or more rude people running a store in my life. If you aren't there for something pipe related, they want nothing to do with you (they are only good at pipe products anyway), and even then, I have seen them be pretty rude to people (they were not so nice to my girlfriend until they realized she was there to buy me a pipe for Christmas).
I only have six pipes, and two of them are Peretti pipes, they smoke ok. I would go in again for nostalgia if I was in Boston, only because an ocean now separates me from Boston. Their blends are ok, but they are riding off of years of tradition and fame. They were nice to me, but I wouldn't go and smoke their blends exclusively, not worth to give them business.
There is a cigar shop down the street that KILLS any competition that Peretti could hope to have, I stopped smoking pipe for a while because I was in there all the time.
