You can get your money back...the best thing to do is ONE person get a lawyer and explain the whole deal. You guys can all go in together and sue him for the money owed. Also yes...you might be out money if you sue him but most judges will make him pay for your attorney fees,court cost, and loss of work if you have to miss due to this. If this is a BIG mis understanding let him tell it to the judge. I don't care if he owes you 50 dollars! This is something you SHOULD do! The more people who put in reports the better your case will hold up.
EDIT: I was reading in the other thread...YES it will cost you money RIGHT now! But believe me you will win your case and will get your money back for the item AND your court cost! This is something that you SHOULD DO! The IC3 reports it to the local PD but it is best for you to contact them too and inform them that you did file a IC3 and explain what is going on. From the looks of this its going to be a FBI case. He not only scam people from GA but he went across stateline and seems as if Canada to. After talking a friend of mine he said that this is not just a "e-bay sale" went bad. He could be looking at jail time over this.
