about a bad buyer Bigboy68

I for one have sold items to Bigboy 68. When I have something that he is interested in he contacts me and asks if I will hold on to it until he receives his check and then he will mail me out a postal money order which I have done twice and both times everything went very smooth, no problems. I am holding that Energy Suspension front sway bar kit for him right now and when the money order gets here I will ship it out to him. He has never asked me to ship something to him before I received his money order. Rob does not have PayPal so he prefers to pay with a postal money order which I have no problem with at all, if it bounces then we are all in big trouble. If you can't afford to wait a while for the money then just say no. I will sell to Rob anytime if I have something that he wants, so far all my dealings with him have been just fine.

Thank you Bob the money order will be in the mail tomorrow

I have to add a little something here. On April 22nd Bigboy 68 told me he wanted to by some items from me, and if I would be so kind as to wait till May 12th when he gets his disability check he would send payment in full. Trying to help a brother out I said sure, I can wait till the 12th. I marked my items as "sale pending" and waited till May 12th. On the 12th Bigboy 68 sent me a pm, saying there would be a one week delay and the payment would go out on the 19th. Again trying to be nice I said "Ok Rob, thanks for letting me know". Well the 19th came and went and no contact. I sent a pm to Rob this morning asking, did you get paid, and did you send payment?
Bigboy 68 responded saying his unemployment check was delayed until Tuesday the 26th, and the money order would go out on Thursday the 28th.
In the mean time I noticed in some of the other for sale ads that Bigboy 68 was telling other people that he wanted to buy their stuff.

So my question for Bigboy 68 is this, is 66Cuda getting the money order that I was suppose to get on the 12th? Or is he getting the money order that I was suppose to get on the 19th? Or have you had 66Cuda waiting even longer that I have been so kind as to wait?
These are rhetorical questions, meaning I don't really expect an answer.

Bigboy 68, I'm not trying to be a dick here, but I have waited on two different payment dates, both of which have come and gone, it's been a month, and now you want me to wait longer.
I Will Not, our deal is off. As you said in an earlier post "this is America any anyone can change there mind for any reason". Well I've changed my mind and I have decided not to sell you my items.
