1) they probably answer a lot of questions based on auto-search/reply. A mistake could have led Pikmin 3 to match up with some activision game. They don't have time to deal with stupid questions like this as they already ask people not to ask these kinds of questions on their website.
2) they can't answer the price question, as they aren't in control of what retailers price the game at. If it is a sketchy website online, then why are you buying there in the first place?
