So I was just ripped off $300. A kid I used to work with said that he was trying to get rid of some zips before he left on vacation. I've bought from him before (not the best stuff, but definitely not the worst). So we get to the spot and we are both in are cars, he says he gonna hand it through the window. I ask to see it and he shows it and then I thought he put it in the backpack but didn't. I gave him the 300 and he left. I checked the bag and it was there so I chased him but lost him. What do I do? I know where he lives, what car he drives, and some of my friends could hit him up. Any help is appreciated, I'm really pissed. Obviously retrospect is 20/20 so I'm kicking myself for things I could have done differently. Thanks! Also now I have zero money to spend on green and all I have is a couple of nugs left.
