I usually go through a quarter every few weeks, and picking up another quarter usually costs me 80-120 dollars, which isn't bad for headies around here. For reference, a quarter of AK costs me 130.

A few of my close friends sell, which means that I get to be pretty choosey when I buy.

Also, when I run into hash, I'll usually buy 10 or 11 grams and drive it to my hometown (I'm in college now) for my friends. That usually makes me a good 40 or 50 bucks, and keeps me pretty high.
