How long do you wait to buy a pipe that you like? Are you an impulsive shopper, pulling out the credit card as soon as a pipe catches your eye? Or do you give it a day or two, to let the shape/finish marinate, to see if you really have to have it? I am trying to wait a week or two before buying, in order not to buy every new pipe that I'm attracted to! What about you guys? Be honest!
