Give it a month. When the initial wave of the HK shipment hit a little while back, they went for over $250. That's what I paid for mine. They're hitting en masse, people are going crazy because it's finally available from US sellers, and they're jumping on the high prices to get it quick. Sellers are taking advantage of that.
It's not nearly as limited as the TDK OC Batman because of the U.S. distribution, as previously stated, which you will probably misunderstand again. It's just people being excited, being unwilling to wait, and sellers taking advantage of that and jacking up the price. I highly doubt it will ever become rare.
