That can be tough. Best way that I can think of is to make some Stoner friends, short of that you probably have friends who have Stoner friends. If you're involved with any athletics, there is bound to be two or three people on your team that know who around you sells. Unless you live in Mormonville like I do, it shouldn't be all that difficult. Worst comes to worst, just be honest. You might get ripped off until you learn what prices in your area are like or you know your hook up well enough. Just remember, if you don't like what is being offered, you don't have to buy it and don't trust anyone that says "Give me the money, I'll be right back", you more than likely won't get anything. (duh)
