If I had to guess, I'd say most pipe retailers, online and otherwise, other than the enlightened folks at PC, have decided that pipes and tobacco are bought mostly by men for themselves, and that spouses, kids, grandkids, and other family don't know what Dad wants, exactly, and know he isn't pleased if you get the wrong thing, so they don't pitch the Fathers Day holiday much. I would think they would, but I'm speculating on why they don't. PC is a star in this regard.
