Why are you so surprised by the retail price for a BD that has every format from Disney? What exactly is the point of a post with a disparaging remark? Everyone knows that you don't pay retail. Look at John Carter. The "all" format version was just down to $24.99.
If you honestly think Amazon is saying MSRP's are higher then they really are then report them to the Better Business Bureau. But in this case most 3D blu-ray's, even those without every format have MSRP's of 49.99. I don't know any store that sells them at MSRP though.
