I have some small sense of what's going on, as I am friends with an Australian collector who was going to visit Marek to see the collection. As someone who buys/sells/trades records, I know it is always way preferable to deal in person versus mailorder with its non-cash payments, packing, shipping, risk of loss, paypal chargebacks, etc. Unless Marek had agreed to an exclusivity agreement with Mark regardling the sale of the records, I see no problem with him also selling the records locally. It seems his error was putting records on the set sale list that had already been sold in person. I also think that while it was certainly very nice of Mark to take 32 wantlists and help with the pre-sale of those items, it was adding another layer of complexity to the proceedings which made a scenario like this more likely. Don't get me wrong, I thank Mark for his efforts in trying to make this work, and I was able to purchase one record at a price I thought very fair, but it's hardly surprising how it ended.
