How do you sell drugs on stick RPG?

You need to buy the alarm clock, caffeine pills, and the cell phone. Also a lot of charm and strength, then go down to the red guy in between the pawn shop and the convince shop he'll sell you drugs for $400. After buying drugs go to the bus shop which is on the farthest right at the bottom. You buy a ticket and you have a chance of selling the drugs, or you might get mugged and lose all your money.
