That is bad... and I doubt that counts as an "exclusive" as there would be listings by other smaller businesses or private sellers of the five toy set. I bet there would be a lot of annoyed collectors who did the same as you did, as the five toys were being released this month and there would have been cheaper options.
Maybe it is just exclusively expensive...

At least the Asia exclusive Dinobot set a few months ago came in an exclusive outer box, but was just the five toys in their regular packaging.
