This may not be the center of the pipe universe but I don't know anything closer to it, and all too often after people have posed something having come into stock somewhere, within minutes others post that they have effectively cleaned out the inventory buying up all they had! They even brag about it! So, coincidence? Maybe, but I doubt that 5 minutes after a tobacco thread came up here the supplier gets all cleaned out was totally unrelated. And the guy who was the one who actually brought it up never even got one can. At least there is the other place (they are probably cleaned out too by now). Pure selfish greed or opportunism.
I guess I was raised differently; if I go to a site to buy something I want and they have 8, I might buy 4, and if they only have 6, I might buy 4 or 3, leaving some for someone else. Who knows, maybe the next guy will do the same for me.
