Hmm, i looked at that earlier Buy-it-now, clicked "see other items", and this came up. I thought that it ended unsold before, because I didn't see anything about any buyer. Doesn't it show when something is really bought, as opposed to just ended?
But, you're right, it seems strange if it indeed was sold in the first auction. But lets say this was som kind of shill-sell to raise the price, why would he sell the next, with TWO decks, for a lower price?
