Why do Nintendo game prices never fall?

Seriously, i've always wonder this. Even months after a game has been released it still maintains it's release price, and even if it does fall it only falls by like $5.

Like WWHD which is $50 on Amazon:

Or Tropical Freeze which is still also $50

And unless no one has noticed the Wii U isn't exactly in the best position.

Because Nintendo is associated with very good quality, since the 90's. So everyone is programed to think like that and that's why retailers sell the games at that price. "Oh it's good quality and it's Nintendo, so the price is right" I'm not against that, but sometimes I would like to buy an old game for much less than the original price. :p
