Doesn't surprise me at all.
Many people will bid on things just because they are considered OOP, RARE or similar.
And than you got the people that buy hard to get stuff not because they want it for themselves but because they wanna sell them to make a profit.
A few buyers of Kits I had for sale did that, 2 hours after the received the kit it was back on e-bay with a much higher starting price than what they paid for it and all of a sudden it was the rarest and hardest to find kit in the whole world.
