Need advice as to what to do about a fellow member on here

Ok, first off I won't mention his name as to I want to hear from you all as to what should I do next. I was checking out the parts for sale threads early this month and came across a full exhaust with dp $300 shipped. I jumped on it as I need one for my new 91 R/T. He said he was on an aircraft carrier and wouldn't be back until the end of the month and wanted to know if that was ok. I replied yes I will gladly take it when you get back. I then get a PM on the 11th stating he got back early and sent me his paypal info. I replied I am sending money now. He then replies a few days later (14th) do you want me to ship it to your paypal address. I replied, yes please. This is the last time he has communicated with me. I have sent a total of three PM's to him and tagged for "read". He has read them all and won't even say boo as to when he will ship them, if he will ship them nothing! Paypal shows them as shipped and delivered in Norfolk, VA. This is where he lives/stationed I believe. I live in the south burbs of Chicago.

So, what should be my next move?

Thanks,
