I had a similar experience, trying to get the Dr. Strange 3D steelbook. I guess I waited too long to pre-order it, because when I tried to pre-order it a few days before release, every time I tried to "proceed to checkout," the website kicked the item back out of my cart and said that it was "currently unavailable." So, on the day of release, I went to Best Buy (got there about twenty minutes early) and waited for them to open. There was one guy who was there ahead of me, so I was the second person in the store when it opened. The guy ahead of me was there to get the Dr. Strange steelbook too, but he wasn't looking for the 3D version, so I was the first one in the door, looking for a copy. There were 3 copies of the regular steelbook out for sale and zero copies of the 3D steelbook. I asked a salesperson if there were any available and they said they only got 3 copies in and they were all for customers who had pre-ordered it for store pick up. So from the minute they opened on the day of release, there were zero copies of the 3D steelbook available and 3 copies of the 2D steelbook (all of which were gone by the time I left the store-I'd say within 30 minutes). I ended up just getting the regular 3D edition.
