Price of the expansion version ps4

[Argonas]

hello:
sorry for my bad English
I just saw the price of the store, was to take the expansion, but not anymore, because Square has over € 10 price for the PS4 version, I would like someone with authority within the company explain me the price difference :
1. With other players from other countries (USA, Japan).
2. With other players of the same continent that have translated his version while mine (I'm Spanish) is not. While I pay the same.
3. With other players on the same continent but other platforms that have the expansion at a price if consistent with what already offers, a realistic price.
I hope they realize they are offering their expansion to an exceeding of the game when I had went on sale price.
I would also like to know, that some must have, what are the advantages of paying that price for more.
What's more, if they had you. Put the same price as in use, with the conversion to dollars would have need not have charged € 37. I think putting the expansion to 45 € is outrageous. And I expect an explanation for what they offer me those 45 €, and not worth me the contents of the expansion. That is what you give to everyone, not you charge them more than me. Anything else will have to give more money for that. Do not believe?
