Dude try to relax for a minute, someone saw an ad with a person claiming to sell a bunch of the same shit that Gearhead got screwed out of so it was suggested that he contact that person, nobody is saying to go track the guy down or do anything else, Gearhead e-mailed him, that’s that.
People do shady shit all the time, obviously no one but you knows this guy and the conversation is between him and Gearhead. You said it’s your friend and that it’s a legit deal so leave it alone, if that’s all true then it will come out in the end.
