I see your point entirely, I'm just trying to present how I view convention exclusives when I get them off ebay. For me, paying $85 for the clone trooper pilot bust wasn't unreasonable. Think about a scalper, minimal joy at a convention aside from scoring items to make money. Has to pay $35 to get into SDCC. Now the cost should be spread out over the items he/she picks up, so putting the total on my bust isn't "fair". But I'm not there, not paying entry fee, not paying parking, not taking time off to do it. Would I rather have had Matt luck out and get me one for $50? Sure, I ain't that dumb, but if I have to pay a little more it's not unreasonable. Now if it's not a scalper, but a collector that managed to score a second bust at the same time and he/she's trying to recoup their entry fee, so be it.
I really appreciate any help I get from folks that go (hello, JediMac) to events and if they pass on the deals, great, but I always offer to help out with costs if they want. No one is obligated to help me in any way and I don't feel it's reasonable to expect that. It is part of the overwhelming coolness of JD though. Most, if not all, of the regulars here do that sort of thing for people no problem and it positively rocks. Should there be any doubt, no, I am not charging anyone extra for my spares. In point of fact, I offered them to a couple of people before they asked as a way of repaying people that spend a lot of time helping me out with various items.
For the most part, I was just interjecting the opposing opinion. I just don't think it's entirely reasonable to expect that just because someone is going anyway, that they should pass along an item to someone because they ask and do so for cost. You've got a pretty neat item that's worth more than you paid for it instantly. You could easily trade it for a Jorg Sacul figure I'd guess fairly quickly. Now there's a discrepancy in retail but not necessarily in value.
If someone's asking you to pay more than retail, it's a decision you have to make - what's it worth to me? But to expect someone going to part with some pretty awesome trade bait at cost just because you need
it might not be entirely fair either.
