Buyers beware of John Geitz Jr.

A thread where we could post information about sales between members would be great. I have bought several items from members & most of the time they are great to deal with & I would highly recommend them. It would be nice to have one place to talk about this so members could check & see if someone is worth dealing with. Something like ebay (I know, everyone hates ebay) where they rank sellers & buyers with positive & negative feedback.
Just yesterday I was looking to buy a part from someone on here & I asked if they would give me 1 day to let them know, I was told "...... I will hold it for a day for you.". When I got home from work & logged on to send him a PM asking about where to send the money, just a few hours later, I had a PM from him telling me that he had sold the part out from under me after telling me he would hold it. His justification was that he was getting more money for it than I was paying. I feel that I am old school & would have honored the fact that I told someone the part was theirs even if more money was involved. I would have at least sent a message explaining the situation & giving the original buyer a chance to finalize the deal we had first while explaining to the buyer offering more money that I had to give the first person a chance. I am not going to mention any names but I would if we had somewhere official to post such information. I won't forget it but if it became a pattern we all should know. If he knew whether or not he could take me seriously may have helped also, we have all had people tell us they wanted something & then never heard from them again.
To me, Mopars are not always about the money but a common interest to save these cars. I got my hopes up for a part I wanted & thought was going to be mine just to find out it wasn't. As usual, just my 2 cents, sorry if it is too winded.
