Yuup. This could get real screwy real fast.
I bought several, but I'm not stressing. Either I'll get them or I wont. Worse part would be the mess I'd catch from pre order buyers, but that's a risk I was aware of when I sold them.
As far as his price at C2E2 goes, imho, there was nothing wrong with him jacking up the price (and I had someone pick me up a few copies for S.S. so I paid the inflated price myself).
I was under the impression that he just intended to sell some of them at C2E2, not that they were supposed to be an "exclusive". If that is the case, and this was just the equivalent of a shop variant, then I don't think anyone should throw shade about his pricing, especially if what he had at the show sold out.
Now, if he was rude to Kap, that's a separate issue entirely, and I don't blame him for having a bad taste in his mouth.
