David Simmons (BAD GUY) Non paying bidder

Hello,
My name is Timothy Wildner I am posting this about a non paying bidder. The name he gave me was David Simmons and his reptibid id is Southern_critters.

I sold my dumeril boa on Oct 18 on Reptibid. The reserve was met and I contacted the winning bidder. We exchanged name, address, ect. On Oct 19 He told me to go ship it on the next Monday Oct 25 and he would get a money order out to me right away. I let him know that I would wait until I received the money order to ship. The only thing I heard from him after that is an email on Oct 23 (2 days before he wanted me to ship it) that he sent a money order out that morning. I have emailed him 3 times letting him know it hadn't arrived (first one a week after he apparently sent it). It was coming from TN to PA so it shouldn't have taken this long, even coming regular mail. I hadn't put any terms in the sale such as "Payment due within a week." but him failing to contact me just makes me think he was trying to get it without paying for it.
I saved all the emails we exchanged, and I have a copy of the ad off reptibid.
Well, hope I got everything right on here posting all the required info (my name, his name, ect).
