While I can appreciate giving cash upfront, unforunately some people are just asses who will take your money and run. I used to have a nice dealer who grew his own, and almost always had some on hand. Regardless of price, I always went to him first. Flakes are annoying as shit, and worse are people that ask you to get them something, then disappear for weeks on end. Granted I don't mind smoking their weed, but sometimes if you can't afford that much at a time, it sucks going broke and not being able to eat/pay rent. Best of luck finding a reliable friend!
