I had the same problem with the guy. He sent me a PM on HCS about a can that I mentioned about getting rid of back on Feb 19th. We made a deal to trade his stock can and 60.00 for my slp can we both pay to ship our cans. He text me on a monday saying that his Girl was on her way to ship it. So I sent mine. Just finally got it Wednesday after him ignoring me, sending me excuses, many text and PM's. He only sent me $50 instead of the $60. About the second week after it didn't show up I googled his name and found all these posts about him. I started the post on HCS about where is my can. He will feed you many excuses, girlfriends mom is in the hospotal, phone broke and lost my address, work is busy. Its obvious that all of it is BS. There were some other guys from Maine that know him and were leaning on him about it and I think that helped.
I called Danvers PD and they said they could really do nothing to help. They said to fill out a report at my local PD and have them contact them.
I hope you get your money.
