Here's the deal. He offered a single book for $999 on Ebay. I negotiated it down to $800. I asked for an invoice last night, he worded it incorrectly, and I asked for a corrected version which he sent over this morning. The book's availability never left Ebay though, 12+ hours after I asked for the invoice. It was still available for purchase at noon today when I made one last look to make sure it was the one I wanted. Anyone could have bought it at the "buy now" price Court had it listed at.
I happened to find a cheaper one on here, and of course not knowing or thinking that there was such a close bond shared between the two sellers and that a stink would be raised, I asked Hulk via Ebay to help me get registered on the boards so I could claim it. I canceled the original Ebay invoice because I found what I was looking for. I claimed Hulk's book and paid for it.
I get that Court is upset that the sell went elsewhere. I'm new to this site and wasn't aware that it would come full circle. I just wanted a $700/$800 book at the better price, as any consumer would. If Court had pulled it from Ebay (it was listed as the "last one"), and set it aside for me, I would never have canceled the PayPal invoice and bought from Hulk.
Do what you will, ban/probation/whatever. This has all gotten far sillier than it ever needed to get.
