Yeah if the guy is a friend or even an acquaintance of yours then say "hey bro what the fuck, I'm holding up my end, you have my money and I have nothing to show for it. How does this make both of us look, me for trusting you to deliver and you for not delivering? I don't care if I get my money or product as long as I get one or the other. I've given you one option now here's the other- not only will I beat the motherfuckin piss outta ya but everyone you know within a 500 mile radius will know you're a bitchass thief, and believe me I'm not playin any motherfuckin games. Get me my shit or who knows what the fuck will happen."
Now I've used this approach and it works. Only problem is it's risky and we're only talking about 60 bucks. If the nut get's extremely paranoid he might go to the law. But why? Can you imagine- "There's some guy out to smack the shit outta me cause I didn't deliver the illegal schedule 3 drugs I said I would, please help me officer!" Sorry, not gonna happen. Anyhoo I'd at least smack the guy in private a few times to let him know you're not fuckin around. Now back to my steak, eggs and whey hehe.
