This topic again...

I'll reiterate what I have iterated in the past.

Just because you paid fees to get into the theme park; parking fee and admission fee (box/unit price and sub fee), does not mean that there won't be other costs inside the park (the game). Typically there's costs for food and drink, mini-games, gifts/souvenirs (mog shop items).

It really is not that big of a deal that you make it out to be considering there's plenty of businesses that operate on this model:

Disney World
Disney Land
Universal Studios
______________ (insert name of whatever theme/amusement/roller coaster park near you)
______________ (insert name of whatever golf courses near you)
Sam's Club, Costco, BJ's, _______ (any other bulk seller clubs that require membership)

Or any other business that charges you at the door and also has other fees inside. You don't like it, then don't partake in the optional services, but at the same time don't vilify/demonize people that choose to. This model isn't going to go away.

However, if you want to make a point that the asking price for some of the items is a bit exorbitant, that's fair and a fair point.
